DESCRIPTION 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.
