Preliminary

3A Ultra Low Dropout Linear Regulator

uP7718

Features

General Description

The uP7718 is a 3A ultra low dropout linear regulator Works with 1.2V~5.5V V_IN

specifically designed for motherboard, notebook and graphic

Adjustable Output Voltage, Down to 0.8V

1.5% Initial Accuracy

card applications. This device works with dual supplies, a

control input for the control circuitry and a power input as

low as 1.2V for providing current to output. The uP7718

delivers high-current and ultra-low-drop output voltage as

low as 0.8V for applications where V_OUTis very close to

V_IN.

Excellent Line and Load Regulation

3A Guaranteed Output Current

178mV @ 3A Dropout Voltage

Very Low On-Resistance

The uP7718 features comprehensive control and protection

functions: a power on reset (POR) circuit for monitoring

both control and power inputs for proper operation; an EN

input for enabling or disabling the device, a power OK with

time delay for indicating the output voltage status, a

foldback current limit function, and a thermal shutdown

function.
