APE8800A

Note：To prevent oscillation, it is recommended to use minimum 1µF X7R or X5R dielectric capacitors if ceramics are

used as input/output capacitors.

Pin Function

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 from oscillation.

The

APE8800A

is stable with an output capacitor 1µF or greater. The larger output capacitor will be required for

application with larger load transients. The large output capacitor could reduce output noise, improve stability,

and PSRR.
