■ Fixed Output Voltage: 1.5V, 2.5V, 3.0V,
3.3V and 5V (SOT223 only)
■ Available Packages: SOT-223,TO-252,
TO-220, and TO-263
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 1.5, 2.5V, 3.0V, 3.3V and 5.0V 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 10F or larger, provides unconditionally
stability for most applications.
