1A, 6V, Ultra Low Dropout Linear Regulator

RT2517A

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.
