1A LOW DROPOUT ADJUSTA BLE AND FIXED-MODE REGULATOR WITH ENABLE
Description
The AP7361C is a 1A, adjustable and fixed output volt age, ultra-low
dropout linear regulat or with enable. T he device i ncludes pass
element, error amplifi er, band-gap reference, current limit and thermal
shutdown circ uitry. The device is turned on when EN pin is set to logic
high level.
The characterist ics of the low dropout voltage and low quiescent
current make it suitable for low-to-medium power applications; for
example, lapt op computers, audi o and video applications, and
battery-powered devices . The typic al qui escent current is
approximately 60µA . Bu ilt-in current-limit and thermal-shutdown
functions prevent I C from damage in fault conditions.
The AP7361C is available in U-DFN3030-8 (Type E), SOT89-5,
SOT223, TO252 (DPAK) and SO-8EP packages.
