1.2A LOW DROPOUT REGULATOR WITH POK
Description
Pin Assignments
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 are available in DFN3030-10 and SOP-8L
packages.
