DESCRIPTION  
Portable/Palm Top/Notebook  
Computers  
Battery Chargers  
The SPX2810 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 SPX2810 has a very low  
quiescent current and a low dropout voltage of 1.1V at full load. As output current decreases,  
quiescent current flows into the load, increasing efficiency. SPX2810 is available in adjustable  
or fixed 2.5V, 3.0V and 3.3V output voltages.  
The SPX2810 is offered in several industry standard 3-pin surface mount packages: SOT-223,  
TO-252, TO-220 and TO-263. An output capacitor of 10µF or larger, provides unconditionally  
stability for most applications.
