Description

The AP130 is a 300mA, fixed output voltage, low dropout

linear regulator. The device includes pass element, error

amplifier, band-gap, current-limit and thermal shutdown

circuitry. 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, results in extensively fixed output voltage versions

and make it convenient to use for applications. Built-in

current-limit and thermal-shutdown functions prevent any

fault condition from IC damage.
