The AP7361E 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.
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 60µA. Built-in current-limit, thermal-shutdown and power good functions prevent IC from damage in fault conditions. The AP7361E is available in U-DFN3030-8 (Type E) package.
