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.
