150mA OmniPowerTM LDO Linear Regulator General Description
The AAT3201 PowerLinearTM OmniPower Low Dropout Linear Regulator is ideal for systems where a low cost solution is critical. This device features extremely low quiescent current which is typically 20A. Dropout voltage is also very low, typically 200mV. The AAT3201 has an Enable pin feature, which when pulled low will enter the LDO regulator into a shutdown mode removing power from its load and offering extended power conservation capabilities for portable battery powered applications. The AAT3201 has output short circuit and over current protection. In addition, the device also has an over temperature protection circuit, which will shutdown the LDO regulator during extended over-current events. The AAT3201 is available in the space saving 5-pin SOT23 package. The device is rated over a -40C to 85C temperature range. Since only a small, 1F ceramic output capacitor is recommended, the AAT3201 is a truly cost effective voltage conversion solution. The AAT3201 is similar to the AAT3200 with the exception that it offers further power savings with its enable pin.

Functional Description
The AAT3201 is intended for LDO regulator applications where output current load requirements range from No Load to 150mA. The advanced circuit design of the AAT3201 has been optimized for use as the most cost effective solution. The typical quiescent current level is just 20A. The AAT3201 also contains an enable circuit, which has been provided to shutdown the LDO regulator for additional power conservation in portable products. In the shutdown state the LDO draws less than 1A from input supply. The LDO also demonstrates excellent power supply rejection ratio (PSRR), and load and line transient response characteristics.
The LDO regulator output has been specifically optimized to function with low cost, low ESR ceramic capacitors. However, the design will allow for operation with a wide range of capacitor types. The AAT3201 has complete short circuit and thermal protection. The integral combination of these two internal protection circuits give the AAT3201 a comprehensive safety system to guard against extreme adverse operating conditions. Device power dissipation is limited to the package type and thermal dissipation properties. Refer to the thermal considerations section for details on device operation at maximum output load levels.

150mA OmniPowerTM LDO Linear Regulator Applications Information
To assure the maximum possible performance is obtained from the AAT3201, please refer to the following application recommendations. The total output capacitance required can be calculated using the following formula: COUT = Where: I = maximum step in output current V = maximum excursion in voltage that the load can tolerate Note that use of this equation results in capacitor values approximately two to four times the typical value needed for an AAT3201 at room temperature. The increased capacitor value is recommended if tight output tolerances must be maintained over extreme operating conditions and maximum operational temperature excursions. If tantalum or aluminum electrolytic capacitors are used, the capacitor value should be increased to compensate for the substantial ESR inherent to these capacitor types. I x 15F V
AAT3201
Input Capacitor
Typically a 1F or larger capacitor is recommended for CIN in most applications. A CIN capacitor is not required for basic LDO regulator operation. However, if the AAT3201 is physically located any distance more than a centimeter or two from the input power source, a CIN capacitor will be needed for stable operation. CIN should be located as close to the device VIN pin as practically possible. CIN values greater than 1F will offer superior input line transient response and will assist in maximizing the power supply ripple rejection. Ceramic, tantalum or aluminum electrolytic capacitors may be selected for CIN as there is no specific capacitor ESR requirement. For 150mA LDO regulator output operation, ceramic capacitors are recommended for CIN due to their inherent capability over tantalum capacitors to withstand input current surges from low impedance sources such as batteries in portable devices.
Capacitor Characteristics
Ceramic composition capacitors are highly recommended over all other types of capacitors for use with the AAT3201. Ceramic capacitors offer many advantages over their tantalum and aluminum electrolytic counterparts. A ceramic capacitor typically has very low ESR, is lower cost, has a smaller PCB footprint and is non-polarized. Line and load transient response of the LDO regulator is improved by using low ESR ceramic capacitors. Since ceramic capacitors are non-polarized, they are less prone to damage if connected incorrectly. Equivalent Series Resistance (ESR): ESR is a very important characteristic to consider when selecting a capacitor. ESR is the internal series resistance associated with a capacitor, which includes lead resistance, internal connections, capacitor size and area, material composition and ambient temperature. Typically capacitor ESR is measured in milliohms for ceramic capacitors and can range to more than several ohms for tantalum or aluminum electrolytic capacitors. Ceramic Capacitor Materials: Ceramic capacitors less than 0.1F are typically made from NPO or COG materials. NPO and COG materials are typically tight tolerance and very stable over temperature. Larger capacitor values are typically composed of X7R, X5R, Z5U and Y5V dielectric materials. 9
Output Capacitor
For proper load voltage regulation and operational stability, a capacitor is required between pins VOUT and GND. The COUT capacitor connection to the LDO regulator ground pin should be made as direct as practically possible for maximum device performance. The AAT3201 has been specifically designed to function with very low ESR ceramic capacitors. Although the device is intended to operate with these low ESR capacitors, it is stable over a very wide range of capacitor ESR, thus it will also work with some higher ESR tantalum or aluminum electrolytic capacitors. However, for best performance, ceramic capacitors are recommended. The value of COUT typically ranges from 0.47F to 10F, however 1F is sufficient for most operating conditions. If large output current steps are required by an application, then an increased value for COUT should be considered. The amount of capacitance needed can be calculated from the step size of the change in output load current expected and the voltage excursion that the load can tolerate.
3201.2002.3.0.91
150mA OmniPowerTM LDO Linear Regulator
Large ceramic capacitors, typically greater than 2.2F are often available in the low cost Y5V and Z5U dielectrics. These two material types are not recommended for use with LDO regulators since the capacitor tolerance can vary more than 50% over the operating temperature range of the device. A 2.2F Y5V capacitor could be reduced to 1F over the full operating temperature range. This can cause problems for circuit operation and stability. X7R and X5R dielectrics are much more desirable. The temperature tolerance of X7R dielectric is better than 15%. Capacitor area is another contributor to ESR. Capacitors, which are physically large in size will have a lower ESR when compared to a smaller sized capacitor of equivalent material and capacitance value. These larger devices can also improve circuit transient response when compared to an equal value capacitor in a smaller package size. Consult capacitor vendor data sheets carefully when selecting capacitors for use with LDO regulators. 140C the system thermal protection circuit will become active. The internal thermal protection circuit will actively turn off the LDO regulator output pass device to prevent the possibility of over temperature damage. The LDO regulator output will remain in a shutdown state until the internal die temperature falls back below the 140C trip point. The interaction between the short circuit and thermal protection systems allow the LDO regulator to withstand indefinite short circuit conditions without sustaining permanent damage.
AAT3201
No-Load Stability
The AAT3201 is designed to maintain output voltage regulation and stability under operational noload conditions. This is an important characteristic for applications where the output current may drop to zero. An output capacitor is required for stability under no load operating conditions. Refer to the output capacitor considerations section for recommended typical output capacitor values.
Enable Function
The AAT3201 features an LDO regulator enable / disable function. This pin (EN) is active high and is compatible with CMOS logic. To assure the LDO regulator will switch on, the EN turn on control level must be greater then 2.4 volts. The LDO regulator will go into the disable shutdown mode when the voltage on the EN pin falls below 0.6 volts. If the enable function is not needed in a specific application, it may be tied to VIN to keep the LDO regulator in a continuously on state.
Thermal Considerations and High Output Current Applications
The AAT3201 is designed to deliver a continuous output load current of 150mA under normal operating conditions. The limiting characteristic for the maximum output load safe operating area is essentially package power dissipation and the internal preset thermal limit of the device. In order to obtain high operating currents, careful device layout and circuit operating conditions need to be taken into account. The following discussions will assume the LDO regulator is mounted on a printed circuit board utilizing the minimum recommended footprint and the printed circuit board is 0.062inch thick FR4 material with one ounce copper. At any given ambient temperature (TA) the maximum package power dissipation can be determined by the following equation: PD(MAX) = [TJ(MAX) - TA] / JA Constants for the AAT3201 are TJ(MAX), the maximum junction temperature for the device which is 125C and JA = 150C/W, the package thermal resistance. Typically, maximum conditions are calculated at the maximum operating temperature where TA = 85C, under normal ambient conditions
Short Circuit Protection and Thermal Protection
The AAT3201 is protected by both current limit and over temperature protection circuitry. The internal short circuit current limit is designed to activate when the output load demand exceeds the maximum rated output. If a short circuit condition were to continually draw more than the current limit threshold, the LDO regulator's output voltage will drop to a level necessary to supply the current demanded by the load. Under short circuit or other over current operating conditions, the output voltage will drop and the AAT3201's die temperature will increase rapidly. Once the regulator's power dissipation capacity has been exceeded and the internal die temperature reaches approximately
10
3201.2002.3.0.91
150mA OmniPowerTM LDO Linear Regulator
TA = 25C. Given TA = 85, the maximum package power dissipation is 267mW. At TA = 25C, the maximum package power dissipation is 667mW. The maximum continuous output current for the AAT3201 is a function of the package power dissipation and the input to output voltage drop across the LDO regulator. Refer to the following simple equation: IOUT(MAX) < PD(MAX) / (VIN - VOUT) For example, if VIN = 5V, VOUT = 2.5V and TA = 25, IOUT(MAX) < 267mA. The output short circuit protection threshold is set between 150mA and 300mA. If the output load current were to exceed 267mA or if the ambient temperature were to increase, the internal die temperature will increase. If the condition remained constant and the short circuit protection did not activate, there would be a potential damage hazard to LDO regulator since the thermal protection circuit will only activate after a short circuit event occurs on the LDO regulator output. To figure what the maximum input voltage would be for a given load current refer to the following equation. This calculation accounts for the total power dissipation of the LDO Regulator, including that caused by ground current. PD(MAX) = (VIN - VOUT)IOUT + (VIN x IGND) This formula can be solved for VIN to determine the maximum input voltage. VIN(MAX) = (PD(MAX) + (VOUT x IOUT)) / (IOUT + IGND) The following is an example for an AAT3201 set for a 2.5 volt output: From the discussion above, PD(MAX) was determined to equal 667mW at TA = 25C. VOUT = 2.5 volts IOUT = 150mA IGND = 20A VIN(MAX)=(667mW+(2.5Vx150mA))/(150mA +20A) VIN(MAX) = 6.95V Thus, the AAT3201 can sustain a constant 2.5V output at a 150mA load current as long as VIN is 6.95V at an ambient temperature of 25C. 5.5V is the maximum input operating voltage for the AAT3201, thus at 25C, the device would not have any thermal concerns or operational VIN(MAX) limits. This situation can be different at 85C. The following is an example for an AAT3201 set for a 2.5 volt output at 85C: From the discussion above, PD(MAX) was determined to equal 267mW at TA = 85C. VOUT = 2.5 volts IOUT = 150mA IGND = 20A VIN(MAX)=(267mW+(2.5Vx150mA))/(150mA+20A) VIN(MAX) = 4.28V Higher input to output voltage differentials can be obtained with the AAT3201, while maintaining device functions in the thermal safe operating area. To accomplish this, the device thermal resistance must be reduced by increasing the heat sink area or by operating the LDO regulator in a duty cycled mode. For example, an application requires VIN = 5.0V while VOUT = 2.5V at a 150mA load and TA = 85C. VIN is greater than 4.28V, which is the maximum safe continuous input level for VOUT = 2.5V at 150mA for TA = 85C. To maintain this high input voltage and output current level, the LDO regulator must be operated in a duty cycled mode. Refer to the following calculation for duty cycle operation: PD(MAX) is assumed to be 267mW IGND = 20A IOUT = 150mA VIN = 5.0 volts VOUT = 2.5 volts %DC = 100(PD(MAX) / ((VIN - VOUT)IOUT + (VIN x IGND)) %DC=100(267mW/((5.0V-2.5V)150mA+(5.0Vx20A)) %DC = 71.2% For a 150mA output current and a 2.5 volt drop across the AAT3201 at an ambient temperature of 85C, the maximum on time duty cycle for the device would be 71.2%. The following family of curves shows the safe operating area for duty cycled operation from ambient room temperature to the maximum operating level.

150mA OmniPowerTM LDO Linear Regulator
High Peak Output Current Applications
Some applications require the LDO regulator to operate at continuous nominal levels with short duration high current peaks. The duty cycles for both output current levels must be taken into account. To do so, one would first need to calculate the power dissipation at the nominal continuous level, then factor in the addition power dissipation due to the short duration high current peaks. For example, a 2.5V system using a AAT3221/ 2IGV-2.5-T1 operates at a continuous 100mA load current level and has short 150mA current peaks. The current peak occurs for 378s out of a 4.61ms period. It will be assumed the input voltage is 5.0V. First, the current duty cycle percentage must be calculated: Device Duty Cycle vs. V DROP VOUT = 2.5V @ 50 degrees C

Next, the continuous nominal power dissipation for the 100mA load should be determined then multiplied by the duty cycle to conclude the actual power dissipation over time.

150mA OmniPowerTM LDO Linear Regulator
The power dissipation for a 100mA load occurring for 91.8% of the duty cycle will be 229.5mW. Now the power dissipation for the remaining 8.2% of the duty cycle at the 150mA load can be calculated: PD(MAX) = (VIN - VOUT)IOUT + (VIN x IGND) PD(150mA) = (5.0V - 2.5V)150mA + (5.0V x 20A) PD(150mA) = 375mW PD(8.2%D/C) = %DC x PD(150mA) PD(8.2%D/C) = 0.082 x 375mW PD(8.2%D/C) = 30.75mW The power dissipation for a 150mA load occurring for 8.2% of the duty cycle will be 20.9mW. Finally, the two power dissipation levels can summed to determine the total true power dissipation under the varied load. PD(total) = PD(100mA) + PD(150mA) PD(total) = 229.5mW + 30.75mW PD(total) = 260.25mW The maximum power dissipation for the AAT3201 operating at an ambient temperature of 85C is 267mW. The device in this example will have a total power dissipation of 260.25mW. This is within the thermal limits for safe operation of the device.
AAT3201
Printed Circuit Board Layout Recommendations
In order to obtain the maximum performance from the AAT3201 LDO regulator, very careful attention must be considered in regard to the printed circuit board layout. If grounding connections are not properly made, power supply ripple rejection and LDO regulator transient response can be compromised. The LDO Regulator external capacitors CIN and COUT should be connected as directly as possible to the ground pin of the LDO Regulator. For maximum performance with the AAT3201, the ground pin connection should then be made directly back to the ground or common of the source power supply. If a direct ground return path is not possible due to printed circuit board layout limitations, the LDO ground pin should then be connected to the common ground plane in the application layout.
