Pin Discription
Pin Name Pin Number Function
IN 4 The input of the regulator. Bypass to ground through at least 1μF ceramic
capacitor.
OUT 5 The output of the regulator. Bypass to ground through at least 2.2μF ceramic
capacitor. For improved ac load response a larger capacitor is recommended.
GND 2 Ground.
ADJ 3 Adjustable voltage version only – a resistor divider from this pin to the OUT pin
and ground sets the output voltage.
EN 1 Enable input, active high.
NC NA No connection.

AP7361
1A LOW DROPOUT ADJUSTABLE AND FIXED-MODE REGULATOR WITH ENABLE
Description
The AP7361 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
70µA. Built-in current-limit and thermal-shutdown functions prevent
IC from damage in fault conditions.
The AP7361 is available in U-DFN3030-8, SOT89-5, SOT223, TO252
and SO-8EP package.
