1.2A LOW DROPOUT REGULATOR WITH POK  
Description  
Pin Assignments  
( Top View )  
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.
