Description

The SPX1117T-L is a low power positive-voltage regulator designed to satisfy moderate power requirements with a cost-effective, small footprint solution. It is an excellent choice for battery-powered applications and portable computers. The SPX1117T-L features very low quiescent current and a low dropout voltage of 1.1V at a full load. It is available in adjustable or fixed output voltages of 1.5V, 1.8V, 2.5V, 2.85V, 3.0V, 3.3V, and 5V. The device 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.
