General Description
The AT9910 is a high performance positive voltage
regulator designed for use in applications requiring
very low dropout voltage at up to 1 Amps. The AT9910
provides excellent regulation over variations in line,
load and temperature. AT9910 is stable with minimum
4.7µF MLCC (X5R) output capacitor.
The AT9910 is available with 1.8V, 2.5V and 3.3V in-
ternally preset outputs.
