Advanced Power Electronics Corp. APE8865 300mA LOW DROPOUT LINEAR REGULATOR FEATURES DESCRIPTIOON The APE8865 series are low dropout, positive linear regulators with very low quiescent current. The APE8865 can supply 300mA output current with a low dropout voltage at about 250mV. The APE8865 regulator is able to operate with output capacitors as small as 1 µ F for stability. Other than the current limit protection APE8865 also offers on chip thermal shutdown feature providing protection against overload or any condition when the ambient temperature exceeds the junction temperature. The APE8865 series are offering several fixed output voltage types including 1.2V ~ 3.3V. The APE8865 series are available in low-profile, space-saving SC-70-4L 、 SC-70-5L 、 SOT-23 & SOT23-5L packages. Low Dropout Voltage of 250mV at 300mA Guaranteed 300mA Output Current Very Low Quiescent Current at about 30uA ±2% Output Voltage Accuracy for 1.2V~3.3V Needs Only 1µF Capacitor for Stability Thermal Shutdown Protection Current Limit Protection Output Voltage Fast Discharge Low-ESR Ceramic Capacitor for Output Stability.

APE8865 PIN DESCRIPTIONS PIN SYMBOL PIN DESCRIPTION VIN Power is supplied to this device from this pin which is required an input filter capacitor. In general, the input capacitor in the range of 1µF to 10µF is sufficient. The output supplies power to loads. The output capacitor is required to prevent output voltage unstable. The VOUT APE8865 is stable with an output capacitor 1µF or greater. The larger output capacitor will be required for application with large transit load to limit peak voltage transits, besides could reduce output noise, improve stability, PSRR.
