50mA, 100mA and 150mA Adjustable CMOS LDOs with Shutdown
Features
* * * * * * * * Zero Ground Current for Longer Battery Life Adjustable Output Voltage Very Low Dropout Voltage Choice of 50mA (TC1070), 100mA (TC1071) and 150mA (TC1187) Output Power-Saving Shutdown Mode Over Current and Over Temperature Protection Space-Saving 5-Pin SOT-23A Package Pin Compatible with Bipolar Regulators
General Description
The TC1070, TC1071 and TC1187 are adjustable LDOs designed to supersede a variety of older (bipolar) voltage regulators. Total supply current is typically 50A at full load (20 to 60 times lower than in bipolar regulators). The devices' key features include ultra low noise operation, very low dropout voltage - typically 85mV (TC1070); 180mV (TC1071); and 270mV (TC1187) at full load, and fast response to step changes in load. Supply current is reduced to 0.5A (max) when the shutdown input is low. The devices incorporate both over-temperature and over-current protection. Output voltage is programmed with a simple resistor divider from VOUT to ADJ to GND. The TC1070, TC1071 and TC1187 are stable with an output capacitor of only 1F and have a maximum output current of 50mA, 100mA and 150mA, respectively. For higher output versions, please see the TC1174 (IOUT = 300mA) data sheet.

Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from 0.1mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value. Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a current pulse equal to ILMAX at VIN = 6V for T = 10 msec. The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction-to-air (i.e., TA, TJ, JA). Exceeding the maximum allowable power dissipation causes the device to initiate thermal shutdown. Please see Section 4.0 Thermal Considerations for more details.. The minimum VIN has to justify the conditions: VIN VR + VDROPOUT and VIN 2.7V for IL = 0.1mA to I OUTMAX.

3.0 DETAILED DESCRIPTION
3.1 Adjust Input
The TC1070, TC1071 and TC1187 are adjustable fixed output voltage regulators. (If a fixed version is desired, please see the TC1014/TC1015/TC1185 data sheet.) Unlike bipolar regulators, the TC1070, TC1071 and TC1187 supply current does not increase with load current. In addition, VOUT remains stable and within regulation over the entire 0mA to IOUTMAX operating load current range, (an important consideration in RTC and CMOS RAM battery back-up applications). Figure 3-1 shows a typical application circuit. The regulator is enabled any time the shutdown input (SHDN) is at or above VIH, and shutdown (disabled) when SHDN is at or below VIL. SHDN may be controlled by a CMOS logic gate, or I/O port of a microcontroller. If the SHDN input is not required, it should be connected directly to the input supply. While in shutdown, supply current decreases to 0.05A (typical), VOUT falls to zero volts. The output voltage setting is determined by the values of R1 and R2 (Figure 3-1). The ohmic values of these resistors should be between 470K and 3M to minimize bleeder current. The output voltage setting is calculated using the following equation.
EQUATION 3-1:
VOUT = VREF x
[ R1 R2
+ 1]
The voltage adjustment range of the TC1070, TC1071 and TC1187 is from VREF to (VIN - 0.05V). If so desired, a small capacitor (100pF to 0.01F) may be added to the ADJ input to further reduce output noise.

A 1F (min) capacitor from VOUT to ground is recommended. The output capacitor should have an effective series resistance greater than 0.1 and less than 5.0, and a resonant frequency above 1MHz. A 1F capacitor should be connected from VIN to GND if there is more than 10 inches of wire between the regulator and the AC filter capacitor, or if a battery is used as the power source. Aluminum electrolytic or tantalum capacitor types can be used. (Since many aluminum electrolytic capacitors freeze at approximately -30C, solid tantalums are recommended for applications operating below -25C.) When operating from sources other than batteries, supply-noise rejection and transient response can be improved by increasing the value of the input and output capacitors and employing passive filtering techniques.

4.1
THERMAL CONSIDERATIONS
Thermal Shutdown
Equation 4-1 can be used in conjunction with Equation 4-2 to ensure regulator thermal operation is within limits. For example: Given: VINMAX = 3.0V 10% VOUTMIN = 2.7V - 2% ILOADMAX = 40mA TJMAX TAMAX = 125C = 55C
Integrated thermal protection circuitry shuts the regulator off when die temperature exceeds 160C. The regulator remains off until the die temperature drops to approximately 150C.
4.2
Power Dissipation
The amount of power the regulator dissipates is primarily a function of input and output voltage, and output current. The following equation is used to calculate worst case actual power dissipation:
Find: 1. Actual power dissipation 2. Maximum allowable dissipation Actual power dissipation: PD (VINMAX - VOUTMIN)ILOADMAX = [(3.0 x 1.10) - (2.7 x .0.98)]40 x 10-3 = 26.2mW Maximum allowable power dissipation: PDMAX = (T JMAX - TAMAX) JA = (125 - 55) 220 = 318mW In this example, the TC1070 dissipates a maximum of 26.2mW; below the allowable limit of 318mW. In a similar manner, Equation 4-1 and Equation 4-2 can be used to calculate maximum current and/or input voltage limits.
EQUATION 4-1:
PD (VINMAX - VOUTMIN)ILOADMAX Where: PD VINMAX VOUTMIN ILOADMAX = Worst case actual power dissipation = Maximum voltage on VIN = Minimum regulator output voltage = Maximum output (load) current
The maximum allowable power dissipation (Equation 4-2) is a function of the maximum ambient temperature (TAMAX), the maximum allowable die temperature (TJMAX) and the thermal resistance from junction-to-air (JA). The 5-Pin SOT-23A package has a JA of approximately 220C/Watt.
EQUATION 4-2:
PDMAX = (TJMAX - TAMAX) JA Where all terms are previously defined.
4.3
Layout Considerations
The primary path of heat conduction out of the package is via the package leads. Therefore, layouts having a ground plane, wide traces at the pads, and wide power supply bus lines combine to lower JA and therefore increase the maximum allowable power dissipation limit.
