Rx5RW SERIES
ULTRA SMALL PACKAGE VOLTAGE REGULATOR
NO.EA-048-111020
OUTLINE
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 volt-age and a current limit circuit.
The output voltage of these ICs is fixed with high accuracy.
Even if V
OUT
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.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field.
The functional operation at or over these absolute maximum ratings is not assured.
