RT9164
1A Fixed and Adjustable Low Dropout
Positive Voltage Regulators
General Description
The RT9164 series of high performance positive
voltage regulators is designed for applications
requiring low dropout performance at fully rated
current. Additionally, the RT9164 series provides
excellent regulation over variations in line and load.
