NCP623 Ultra Low Noise 150 mA Low Dropout Voltage Regulator with ON/OFF Control
The NCP623 low dropout linear regulator can deliver up to 150 mA of output current with a typical dropout voltage of 180 mV. This low dropout feature helps to maintain a regulated output voltage for a longer period of time as the lifetime of the battery decreases. It is the ideal choice for noise sensitive environments like portable applications where noise performance and space are at a premium. The typical output noise voltage specification is 25 mVRMS. The space saving package choices include a Micro8TM or DFN6. An additional noise saving feature of this device is its ability to filter choppy signals on the power supply by providing a typical DC ripple rejection of -90 dB and -70 dB at 1.0 kHz. The NCP623 is designed to work with very low ESR capacitors such as ceramic capacitors which are common in the industry now. Additional features such as thermal shutdown and short-circuit protection provide for a robust system design.

NCP623
DEFINITIONS Load Regulation - The change in output voltage for a change in load current at constant chip temperature. Dropout Voltage - The input/output differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 100 mV below its nominal value (which is measured at 1.0 V differential), dropout voltage is affected by junction temperature, load current and minimum input supply requirements. Output Noise Voltage - The RMS AC voltage at the output with a constant load and no input ripple, measured over a specified frequency range. Maximum Power Dissipation - The maximum total dissipation for which the regulator will operate within specifications. Quiescent Current - Current which is used to operate the regulator chip and is not delivered to the load. Line Regulation - The change in input voltage for a change in the input voltage. The measurement is made under conditions of low dissipation or by using pulse techniques such that the average chip temperature is not significantly affected. Line Transient Response - Typical over- and undershoot response when input voltage is excited with a given slope. Thermal Protection - Internal thermal shutdown circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. When activated, typically 150C, the regulator turns off. This feature is provided to prevent catastrophic failures from accidental overheating. Maximum Package Power Dissipation - The maximum package power dissipation is the power dissipation level at which the junction temperature reaches its maximum value i.e. 125C. The junction temperature is rising while the difference between the input power (VCC X ICC) and the output power (Vout X Iout) is increasing. Depending on ambient temperature, it is possible to calculate the maximum power dissipation, maximum load current or maximum input voltage (see Application Hints: Protection). The maximum power dissipation supported by the device is a lot increased when using appropriate application design. Mounting pad configuration on the PCB, the board material and also the ambient temperature are affected the rate of temperature rise. It means that when the IC has good thermal conductivity through PCB, the junction temperature will be "low" even if the power dissipation is great. The thermal resistance of the whole circuit can be evaluated by deliberately activating the thermal shutdown of the circuit (by increasing the output current or raising the input voltage for example). Then you can calculate the power dissipation by subtracting the output power from the input power. All variables are then well known: power dissipation, thermal shutdown temperature (150C for NCP623) and ambient temperature.

APPLICATION HINTS Input Decoupling - As with any regulator, it is necessary to reduce the dynamic impedance of the supply rail that feeds the component. A 1.0 mF capacitor either ceramic or tantalum is recommended and should be connected close to the NCP623 package. Higher values will correspondingly improve the overall line transient response. Output Decoupling - Output capacitors exhibiting ESRs ranging from a few mW up to 3.0 W can safely be used. The minimum decoupling value is 1.0 mF and can be augmented to fulfill stringent load transient requirements. The regulator works with ceramic chip capacitors as well as tantalum devices. Noise Performances - Unlike other LDOs, the NCP623 is a true low-noise regulator. With a 10 nF bypass capacitor, it typically reaches 25 mVRMS overall noise between 100 Hz and 100 kHz. Spectral density graphics as well as noise dependency versus bypass capacitor information is included in this datasheet. The bypass capacitor impacts the startup phase of the NCP623 as depicted by the data-sheet curves. A typical 1.0 ms settling time is achieved with a 10 nF bypass capacitor. However, due to its low-noise architecture, the NCP623 can operate without bypass and thus offers a typical 20 ms startup phase. In that case, the typical output noise stays lower than 65 mVRMS between 100 Hz - 100 kHz. Protections - The NCP623 includes several protections functions. The output current is internally limited to a minimum of 175 mA while temperature shutdown occurs if the die heats up beyond 150C. These value lets you assess the maximum differential voltage the device can sustain at a given output current before its protections come into play. The maximum dissipation the package can handle is given by:
T -T A P max + Jmax R qJA
If a 150 mA output current is needed, the ground current is extracted from the data-sheet curves: 6.5 mA @ 150 mA. For a NCP623NW28R2 (2.8 V), the maximum input voltage will then be 6.48 V, a rather comfortable margin. Typical Application - The following figure portraits the typical application for the NCP623 where both input/output decoupling capacitors appear.

If TJmax is internally limited to 150C, then the NCP623 can dissipate up to 595 mW @ 25C. The power dissipated by the NCP623 can be calculated from the following formula:

NCP623 Wake-up Improvement - In portable applications, an immediate response to an enable signal is vital. If noise is not a concern, the NCP623 without a bypass capacitor settles in nearly 20 ms and typically delivers 65 mVRMS between 100 Hz and 100 kHz. In ultra low-noise systems, the designer needs a 10 nF bypass capacitor to decrease the noise down to 25 mVRMS between 100 Hz and 100 kHz. With the addition of the 10 nF capacitor, the wake-up time expands up to 1.0 ms as shown on the data-sheet curves. If an immediate response is wanted, Figure 5 provides a solution to charge the bypass capacitor with the enable signal without degrading the noise response of the NCP623. At power-on, C4 is discharged. When the control logic sends its wake-up signal by going high, the PNP base is momentarily tied to ground. The PNP switch closes and immediately charges the bypass capacitor C1 toward its operating value. After a few ms, the PNP opens and becomes totally transparent to the regulator. This circuit improves the response time of the regulator which drops from 1.0 ms down to 30 ms. The value of C4 needs to be tweaked in order to avoid any bypass capacitor overload during the wake-up transient.
