AP7365 600mA, LOW QUIESCENT CURRENT FAST TRANSIENT LOW DROPOUT LINEAR REGULATOR Description Pin Assignments The AP7365 is a 600mA, adjustable and fixed output voltage, low (Top View) (Top View ) dropout linear regulator. This device includes pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry. The IN IN 1 5 OUT 1 5 OUT device is turned on when EN pin is set to logic high level. GND 2 GND 2 The characteristics of low dropout voltage and low quiescent current EN 3 4 ADJ EN 3 4 NC make it suitable for low power applications such as battery powered devices. The typical quiescent current is approximately 35A. Built-in SOT25 (Fixed Output) SOT25 (ADJ Output) current-limit and thermal-shutdown functions prevent IC from damage (Top View) (Top View) in fault conditions. ADJ NC EN EN 1 6 1 6 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, 2 5 2 5 GND NC GND NC 3.0V, 3.3V and 3.9V outputs.
