AP7361C 1A LOW DROPOUT ADJUSTABLE AND FIXED-MODE REGULATOR WITH ENABLE Description Pin Assignments The AP7361C is a 1A, adjustable and fixed output voltage, ultra-low dropout linear regulator with enable. The device includes pass (Top View) (Top View) element, error amplifier, band-gap reference, current limit and thermal shutdown circuitry. The device is turned on when EN pin is set to logic OUT 1 8 IN 1 EN 5 OUT high level. 2 7 NC NC GND 2 GND GND The characteristics of the low dropout voltage and low quiescent 3 6 NC ADJ/NC current make it suitable for low to medium power applications, for 3 4 IN example, laptop computers, audio and video applications and battery GND 4 5 ADJ/NC EN powered devices. The typical quiescent current is approximately 60A. Built-in current-limit and thermal-shutdown functions prevent U-DFN3030-8 (Type E) SOT89-5 IC from damage in fault conditions. The AP7361C is available in U-DFN3030-8 (Type E), SOT89-5, (Top View) (Top View) SOT223, TO252 (DPAK) and SO-8EP packages.
