The AP7361EA is a 1A, adjustable and fixed output voltage, ultra-low dropout linear regulator with enable function. The device includes pass elements, error amplifiers, band-gap references, current limiting capability, and thermal shutdown circuitry. The device is turned on when the EN pin is set to a logic-high level. The characteristics of the low dropout voltage and low quiescent
current make it suitable for low- to medium-power applications such as laptop computers, audio/video equipment, and battery-powered devices. The typical quiescent current is approximately 68µA. Built-in current-limiting and thermal-shutdown functions prevent the IC from sustaining damage under fault conditions. The AP7361EA is available in the U-DFN3030-8 (Type E), SOT89-5, SOT223, TO252 (DPAK), and SO-8EP packages.
