Document number: DS31333 Rev. 12 - 3 7 of 12 www.diodes.com September 2017 © Diodes Incorporated AP7115 Application Note Input Capacitor A 1µF input capacitor is required between the AP7115 input pin and GND. There are no requirements for the ESR on input capacitor, but tolerance and temperature coefficient must be considered. Output Capacitor The AP7115 can work with very small ceramic output capacitors (1µF or greater). Higher capacitance values help to improve transient. The output capacitor’s ESR is critical because it from a zero to provide phase lead which is required for loop stability. Figure below is Cout ESR vs. Load Current. Band-Gap Bypass Capacitor 0.1µF bypass capacitor Between BP pin and GND can reduce output voltage noise. Shutdown Input Operation The AP7115 is shutdown by pulling the EN pin low, and turned on by driving the input high. If the shutdown feature is not required, the EN pin should be tied to VIN to keep the regulator on at all time. Dropout Voltage VDROPOUT = VIN - VOUT = RDS(ON) × IOUT Current Limit The AP7115 monitors and controls the PMOS’ gate voltage, limiting the output current to 250mA (typ.). The output can be shorted to ground for an indefinite period of time without damaging the part.

Document number: DS31333 Rev. 12 - 3 8 of 12 www.diodes.com September 2017 © Diodes Incorporated AP7115 Application Note (Cont.) PCB Layout Optimum performance can only be achieved when the device is mounted on a PC board according to the diagram below: Thermal Considerations Thermal Shutdown Protection limits power dissipation in AP7115. When the operation junction temperature exceeds +155° C, the Over Temperature Protection circuit starts the thermal shutdown function and turns the pass element off. The pass element turn s on again after the junction temperature cools by +30° C. For continuous operation, do not exceed absolute maximum operation junction temperature +125° C. The power dissipation definition in device is: PD = (VIN − VOUT) x IOUT + VIN x IQ The maximum power dissipation depends on the thermal resistance of IC package, PCB layout, the rate of surroundings airflow a nd temperature difference between junction to ambient. The maximum power dissipation can be calculated by the following formula: PD(MAX) = ( TJ(MAX) - TA ) / θJA Where T J(MAX) is the maximum operation junction temperature +125° C, TA is the ambient temperature and the θ JA is the junction to ambient thermal resistance.
