description
The SPX2810 is a low power, positive voltage regulator designed to
supply up to 1A of output current. This device is an excellent choice
for use in battery-powered applications and portable computers that
require low dropout, fast transient responses. The SPX2810 features
very low quiescent current and a very low dropout voltage of 1.2V at
full load. This device is available with either an adjustable or a fixed
2.5V, 3.0V, or 3.3V output voltage.
The SPX2810 is offered in industry standard 3-pin SOT-223, TO-220,
TO-252 and TO-263 surface mount packages. An output capacitor of
10F or larger, as required by most high current regulators, assures
output stability.
