The SPX2815 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 SPX2815 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. SPX2815 is available in adjustable
or fixed 2.5V, 3.3V and 5.0V output voltages.
The SPX2815 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.
