The AP7167 is a 1.2A, adjustable output voltage, ultra-low

dropout linear regulator. The device includes pass element, error

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

circuitry. The device is turned on when EN pin is set to logic high

level.

A Power-OK (POK) output is available for power

sequence control.

The characteristics of the low dropout voltage and low quiescent

current make it suitable for low to medium power applications, for

example, laptop computers, audio and video applications, and

battery powered devices. The typical quiescent current is

approximately 125µA.

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

from damage in fault conditions. The AP7167 is available in

DFN3030-10 package.
