SPX1117 - 800mA Low Dropout Voltage Regulator

Datasheet Summary

Description

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.

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 3-pin SOT-223 and TO-263 surface mount packages. An output capacitor of 10µF provides unconditional stability while a smaller 2.2µF capacitor is sufficient for most.
