The SPX1587 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 SPX1587 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. SPX1587 is available in adjustable or fixed 1.5V, 1.8V, 2.5V, 3.3V and 5.0V output voltages.

The SPX1587 is offered in several 3-pin surface mount packages: TO-252, TO-220 and TO-263. An output

capacitor of 10碌F ceramic or tantalum provides unconditional stability.
