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 、
TSOT-23-5L & SOT-23-5L packages.

Note 1:The dropout voltage is defined as V IN-VOUT, which is measured when VOUT drop about 100mV.
Note 2:Regulation is measured at a constant junction temperature by using 30ms current pulse and load regulation in the load range from
0mA to 300mA.

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.
