1A, 6V, Ultra-Low Dropout Linear Regulator
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)
