SMALL PACKAGE VOLTAGE REGULATOR
RQ5RW SERIES
OUTLINE
The RQ5RW Series are voltage regulator ICs with high accuracy output voltage and ultra-low supply current developed by
CMOS process. Each of these ICs consists of 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
is shorted to GND, the included current limit circuit protects the ICs from the destruction.
OUT
Furthermore, these ICs have a chip enable function, so that the supply current on standby can be minimized.
Since the package for these ICs are SC-82AB(Super Mini-mold)package, high density mounting of the ICs on boards is pos-
sible.
