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 VOUT is shorted to GND, the included current limit circuit protects the ICs from the destruction.
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.

ABSOLUTE MAXIMUM RATINGS
Absolute Maximum ratings are threshold limit values that must not be exceeded even for an instant under
any conditions. Moreover, such values for any two items must not be reached simultaneously. Operation
above these absolute maximum ratings may cause degradation or permanent damage to the device. These
are stress ratings only and do not necessarily imply functional operation below these limits.

In RQ5RW Series, a constant voltage can be obtained without using Capacitor C1 and C2. However, when the wire con-
nected VIN is long, use Capacitor C1. Output noise can be reduced by using Capacitor 2.
Insert Capacitors C1 and C2 with the capacitance of 0.1µF to 0.2µF between Input/Output Pins and GND Pin with mini-
mum wiring.
