AP7361 Linear Regulator

Diodes' AP7361 is a 1 A, 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. 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 70 μA. Built-in current-limit and thermal-shutdown functions prevent IC damage in fault conditions.
