Note 2：To prevent oscillation, it is recommended to use minimum 1µF X7R or X5R dielectric capacitors if ceramics are

used as input/output capacitors.

Functional Pin Description

Pin Name

Pin Function

VIN

Power is supplied to this device from this pin which requires an input filter capacitor.

In general, the input

capacitor in the range of 1µF to 10µF is sufficient.

VOUT

The output supplies power to loads.

The output capacitor is required to prevent output voltage unstable.

The

FP6136 is stable with an output capacitor which is 1µF or greater.

The larger output capacitor will be required

for application with large transit load to limit peak voltage transits.

Besides, it could reduce output noise,

improve stability and PSRR.
