®

The SPX1202 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 SPX1202 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. SPX1202 is available in adjustable

or fixed 2.5V, 3V and 3.3V output voltages.

The SPX1202 is offered in several 3-pin surface mount packages: SOT-223, TO-252, TO-220

and TO-263. An output capacitor of 10µF provides unconditional stability while a smaller 2.2µF

capacitor is sufficient for most applications.
