ULTRA SMALL PACKAGE VOLTAGE REGULATOR RX5RW SERIES 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 rence 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 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.

However, when the wire connected VIN is long, use capacitor C1. Output noise can be reduced with using capacitor 2. Insert capacitors C1 and C2 with the capacitance of 0.1F to 0.22F between input/output pins and GND pin with minimum wiring. 19
