VOLTAGE REGULATOR
R×5RL SERIES
APPLICATION MANUAL
NO.EA-022-0006
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.

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.
