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 the 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 applications, for

example, some battery powered devices. The typical quiescent

current is approximately 50µA from zero to maximum load. Due

to the internal flexible design, it results in extensively fixed output

voltage versions and makes it convenient to use for applications.

Built-in current-limit and thermal-shutdown functions prevent any

fault condition from IC damage. An external capacitor can be

connected to the BP pin and reduce the output noise.
