NEW PRODUCT
1A LOW DROPOUT ADJUSTABLE AND FIXED-MODE REGULATOR WITH ENABLE
Description
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.
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 and thermal-shutdown functions prevent
IC from damage in fault conditions.
The AP7361C is available in U-DFN3030-8 (Type E), SOT89-5,
SOT223, TO252 (DPAK) and SO-8EP packages.
