The AP131 is a 300mA, fixed output voltage, low

dropout linear regulator. The Device included pass

element, error amplifier, band-gap, current limit and

thermal shutdown circuitry. The device is ON when

EN pin is set to logic high level.

The characteristics of low dropout voltage and less

quiescent current make it good for some critical

current application, for example, some battery

powered devices. The typical quiescent current is

approximately 50µA from zero to maximum load.

Due to internal flexible design, result in extensively

fixed

convenient

current-limit

prevent any fault condition from IC damage. An

external capacitor can be connected to the BP pin

and reduce the output noise.
