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 10µF ceramic or tantalum provides unconditional stability.
