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.
