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 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. (Top View) OUT 1 8 IN 7 NC ADJ/NC 3 6 NC GND 4 5 EN PRODUCT NEW INFORMATION ADVANCE NC 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 60A. Built-in current-limit and thermal-shutdown functions prevent IC from damage in fault conditions.
