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

10µF or larger, as required by most high current regulators, assures

output stability.
