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 refe r-
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 V
OUT
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 package s for these ICs are SC-82AB (Super Mini-mold) package and SON1612-6(Under
Development), high de nsity mounting of the ICs on boards is possible.
