AT9915
General Description
The AT9915 is a high performance positive voltage
regulator designed for use in applications requiring
very low dropout voltage at up to 1.5 Amps. The
AT9915 provides excellent regulation over variations
in line, load and temperature. AT9915 is stable with
minimum 4.7µF MLCC (X5R) output capacitor.
The AT9915 is available with 1.2V, 1.8V, 2.5V and
3.3V internally preset outputs.
