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 VOUT 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.
FEATURES
Ultra-Low Supply Current............................................. Typ. 1.5µA
(except pull-up/pull-down current for CE /CE pin)
Standby Current ........................................................... Typ. 0.1µA
Dropout Voltage ........................................................... Typ. 40mV (IOUT=1mA, Rx5RW30A/B)
Low Temperature-Drift Coefficient of Output Voltage... Typ. ±100ppm/°C
Excellent Line Regulation ............................................ Typ. 0.05%/V
High Accuracy Output Voltage .....................................±2.0%
Ultra-Small Packages .................................................. SC-82AB (Super Mini-mold), SON1612-6
Built-in Current Limit Circuits
APPLICATIONS
Power source for battery-powered equipment.
Power source for cameras, VCRs, camcorders, hand-held audio instruments and hand-held communication
equipment.
Precision voltage references.
