PRODUCT DESCRIPTION
The SPX2810 is a low power positive voltage regulator designed to source 1A output current. This device is an excellent choice for
use in battery-powered applications and portable computers. The SPX2810 features very low quiescent current and very low dropout
voltage of 1.2V at a full load and lower as output current decreases. This product is available as adjustable or fixed 1.5V, 2.5V, 3.0V,
3.3V, and 5V output voltages.
The SPX2810 is offered in a 3-pin surface mount packages SOT-223, TO-220, TO-252 & DD package. The output capacitor of 10µF
or larger is needed for the output stability of SPX2810 as required by most other regulator circuits
