SPX1117

800mA Low Dropout Voltage Regulator

August 2010

Rev. 2.1.0

GENERAL DESCRIPTION

APPLICATIONS

The SPX1117 is a low power positive-voltage

regulator designed to satisfy moderate power

requirements with a cost effective, small

footprint solution.

 Desktop PC Servers

 Graphic/Video Cards

 Industrial Equipments

 Power Supplies

This device is an excellent choice for use in

battery-powered applications and portable

computers. The SPX1117 features very low

quiescent current and a low dropout voltage of

1.1V at a full load. As output current

decreases, quiescent current flows into the

load, increasing efficiency. SPX1117 is

available in adjustable or fixed 1.5V, 1.8V,

2.5V, 3.3V and 5V output voltages.

FEATURES

 Guaranteed 800mA Output Current

 Guaranteed 1A Peak Current

 Three Terminal Adjustable or Fixed

1.5V, 1.8V, 2.5V, 3.3V and 5V

The SPX1117 is offered in 3-pin SOT-223 and

TO-263 surface mount packages.

 Low Quiescent Current

 Low Dropout Voltage of 1.1V at 800mA

 0.1% Line and 0.2% Load Regulation

 Stable with 2.2µF Ceramic Capacitor

 Overcurrent and Thermal Protection

An output capacitor of 10µF provides

unconditional stability while a smaller 2.2µF

capacitor is sufficient for most applications.

 Lead Free, RoHS Compliant Packages

SOT223 and TO263
