1A LOW DROPOUT ADJUSTABLE AND FIXED-MODE REGULATOR WITH ENABLE

Description

The AP7361 is a 1A, adjustable and fixed output voltage, ultra-low

dropout linear regulator with enable. 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.

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

70µA. Built-in current-limit and thermal-shutdown functions prevent

IC from damage in fault conditions.

The AP7361 is available in U-DFN3030-8, SOT89-5, SOT223, TO252

and SO-8EP package.
