The SPX1117 is a low power positive-voltage regulator designed to satisfy moderate power requiremen
ts with a cost effective, small footprint solution. This device is an excellent choice for u 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 decreas,quiescent current flows into the load, increasing efficiency. SPX1117 is available in adjustable or fixed 1.5V, 1.8V, 2.5V,2.5V, 2.85V, 3.0V, 3.3V and 5V output voltages.
The SPX1117 is offered in veral 3-pin surface mount packages: SOT-223, TO-252, TO-220and TO-263. An output capacitor of 10µF provides unconditional stability while a smaller 2.2µF capacitor is sufficient for most applications.
APPLICATIONS
■ Desktop PC's Servers ■ SCSI-II Active Terminator
■ Portable/ Palm Top / Notebook Computers
■ Cordless Phones ■ Battery Chargers ■ Disk Drives
■ Portable Consumer Equipment ■ Portable Instrumentation ■ SMPS Post-Regulator
