SPX1117

800mA Low Dropout Voltage Regulator

GENERAL DESCRIPTION

APPLICATIONS

• Desktop PC Servers

The SPX1117 is a low power positive-voltage regulator designed to satisfy moderate power requirements with a cost effective, small footprint solution.

• 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 a 3-pin SOT-223 surface mount packages.

• Low Quiescent Current

• Low Dropout Voltage of 1.1V at 800mA

An output capacitor of 10µF provides unconditional stability while a smaller 2.2µF capacitor is sufficient for most applications.

• 0.1% Line and 0.2% Load Regulation
