OUTLINE
The R

5RL Series are voltage regulator ICs with high accuracy output voltage and ultra-low quiescent cur-
rent by CMOS process. Each of these ICs consists of a voltage reference unit, an error amplifier, a driver tran-
sistor, 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.
• Ultra-low Quiescent Current ...........................TYP. 1.1µA (R

• Low Temperature-Drift Coefficient of Output Voltage...............TYP. ±100 ppm/˚C
• Excellent Line Regulation.................................TYP. 0.1%/V
• Output Voltage ..................................................Stepwise setting with a step of 0.1V in the range of 2.0V to 6.0V
is possible (refer to Selection Guide).
• High Accuracy Output Voltage.........................±2.5%
• Three Types of Packages...................................TO-92, SOT-89 (Mini-power Mold), SOT-23-5 (Mini-mold)
