General Description

The AT9911 is a high performance positive voltage

regulator designed for use in applications requiring

very low dropout voltage at up to 1 Amps. The AT9911

provides excellent regulation over variations in line,

load and temperature. AT9911 is stable with minimum

4.7µF MLCC (X5R) output capacitor.

The AT9911 is available with 2.5V internally preset

outputs.
