1.2A LOW DROPOUT REGULATOR WITH POK

Description

Features

The AP7168 is a 1.2A, adjustable output voltage, ultra-low

dropout linear regulator. 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. A Power-OK (POK) output is available for power sequence

control.

•

Wide input voltage range: 2.2V – 5.5V

230mV very low dropout at 500mA load

500mV very low dropout at 1A load

Very low quiescent current (I_Q): 125µA typical

Adjustable output voltage range: 0.8V to 5.0V

Very fast transient response

High PSRR

Accurate voltage regulation

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 125µA.

Current limiting and short circuit protection

Thermal shutdown protection

Stable with any type output capacitor ≥ 4.7µF

Ambient temperature range -40ºC to 85°C

SOP-8L-EP: Available in “Green” Molding Compound

(No Br, Sb)

Built-in current-limit and thermal-shutdown functions prevent

IC from damage in fault conditions. The AP7168 is available in

SOP-8L-EP package.
