VOLTAGE REGULATOR R × 5RL SERIES OUTLINE The R × 5RL Series are voltage regulator ICs with high accuracy output voltage and ultra-low quiescent current by CMOS process. Each of these ICs consists of a voltage reference unit, an error amplifier, a driver transistor, and resistors for setting output voltage. The output voltage is fixed with high accuracy. Three types of packages, TO-92, SOT-89 (Mini-power Mold), SOT-23-5 (Mini-mold), are available. FEATURES • Ultra-low Quiescent Current ....................

R × 5RL TYPICAL APPLICATION In R × 5RL Series, a constant voltage can be obtained VIN VIN C1 + R×5RL SERIES without using Capacitors C1 and C2. However, when the VOUT VOUT + wire connected to Vin is long, use Capacitor C1. Output noise can be reduced by using Capacitor C2. C2 GND Insert Capacitors C1 and C2 with the capacitance of 0.1µF to 2.0µF between Input/Output Pins and GND Pin GND GND with minimum wiring.
