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 (1uF 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. PCB Layout Optimum performance can only be achieved when the device is mounted on a PC board according to the diagram below: AP7115 Region of Stable Cout ESR vs. Load Current 100 Cout ESR (Ω) 10 1 Stable 0.1 0.01 0 20 40 60 80 100 120 140 160 Load Current (mA) 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 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: Band-Gap Bypass Capacitor 0.1uF bypass capacitor Between BP pin and GND can reduces 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 times. Dropout Voltage 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 and temperature difference between junction to ambient. The maximum power dissipation can be calculated by the following formula: PD(MAX) = ( TJ(MAX) - TA ) / θJA Where TJ(MAX) is the maximum operation junction temperature 125°C, TA is the ambient temperature and the θJA is the junction to ambient thermal resistance. 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.
