The RT2517B is a high performance positive voltage regulator designed for use in applications requiring ultra-low input voltage and ultra-low dropout voltage at up to 1A. The feature of ultra-low dropout voltage is ideal for the application 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 RT2517B provides an excellent output voltage regulation over variations in line, load and temperature. Current limit and thermal shutdown protection functions are provided. Additionally, an enable pin is designed to further reduce power consumption while shutdown and the shutdown current is as low as 1.5μA.

The RT2517B is available in the SOP-8 (Exposed Pad) package.
