RT2517A
1A, 6V, Ultra Low Dropout Linear Regulator
General Description
The RT2517A is a high performance positive voltage
regulator designed for applications requiring low input
voltage and ultra low dropout voltage at up to 1A. The
feature of ultra low dropout voltage is ideal for applications
where output voltage is very close to input voltage. The
input voltage can be as low as 2.2V and the output voltage
is adjustable by an external resistive divider. The RT2517A
provides an excellent output voltage regulation over
variations in line, load and temperature. Current limit and
thermal shutdown functions are provided. Additionally, an
enable pin is designed to further reduce power
consumption while shutdown and the shutdown current is
as low as 0.1μA.
The RT2517A is available in the VDFN-8AL 3x3 package.
