SPX1117M3-L-1-5/TR 低压差稳压器

SPX1117M3-L-1-5/TR

低压差稳压器 800mA Low Dropout Voltage Regulator

GENERAL DESCRIPTION SPX1117M3-L-1-5/TR

The SPX1117 is a low power positive-voltage

regulator designed to satisfy moderate power

requirements with a cost effective, small

footprint solution.

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.

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

surface mount packages.

An output capacitor of 10μF provides

unconditional stability while a smaller 2.2μF

capacitor is sufficient for most applications.
