Rx5RW SERIES
NO.EA-048-0602
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 (Super Mini-mold) package and SON1612-6, high density
mounting of the ICs on boards is possible.

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.
