ULTRA SMALL PACKAGE VOLTAGE
REGULATOR
RX5RW SERIES
1
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 refer-
ence 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 VOUT is shorted to GND, the included current limit circuit protects the ICs from the destruc-
tion. 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 (Super Mini-mold) package and SON1612-6(Under
Development), high density mounting of the ICs on boards is possible.
