Nisshinbo Micro Devices Inc. RQ5RW50AA-TR-FE

The Rx5RW Series are CMOS-based voltage regulator ICs with high accuracy output voltage and ultra-low supply current developed. Each of these ICs consists of a driver transistor, a voltage reference unit, an error amplifier, resistors for setting output voltage and a current limit circuit. The output voltage of these ICs is fixed with high accuracy. Even if VOUT is shorted to GND, the included current limit circuit protects the ICs from the destruction. Furthermore, Rx5RWxxA/B have a chip enable function, so that the supply current on standby can be minimized. Since the packages for these ICs are SC-82AB and SON1612-6, high density mounting of the ICs on boards is possible.
