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 (W Package) (W Package) in fault conditions.
