DESCRIPTION

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.

TheSPX2815isofferedinseveral3-pinsurfacemountpackages:TO-252,TO-220andTO-263.

An output capacitor of 10μF ceramic or tantalum provides unconditional stability.
