Description

The AP7365 is a 600mA, adjustable and fixed output voltage,

low dropout linear regulator. The device included pass

element, error amplifier, band-gap, current limit and thermal

shutdown circuitry. The device is turned on when EN pin is

set to logic high level.

The characteristics of low dropout voltage and low quiescent

current make it suitable for low power applications, for

example, battery powered devices. The typical quiescent

current is approximately 35

μA. Built-in current-limit and

thermal-shutdown functions prevent IC from damage in fault

conditions.

This device is available with adjustable output from 0.8V to

5.0V, and fixed version with 0.8V, 1.0V, 1.2V, 1.5V, 1.8V,

2.0V, 2.5V, 2.8V, 3.0V, 3.3V and 3.9V outputs. Please

contact your local sales office for any other voltage options.

The AP7365 is available in SOT25, SOT89/R-3L, SOT223/R-

3L, and DFN2020-6 packages.
