VOLTAGE REGULATOR
Rx5RL SERIES
1
OUTLINE
The Rx5RL Series are CMOS-based voltage regulator ICs with high accuracy output voltage and ultra-low
quiescent current. 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.
Ultra-low Quiescent Current ...........................Typ. 1.1A (Rx5RL30A, V
IN
=5.0V)
Small Dropout Voltage .....................................Typ. 30mV (Rx5RL50A, I
OUT
=1mA)
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)

SELECTION GUIDE
The package type, the output voltage, the packing type, and the taping type of Rx5RL Series can be
designated at the user's request by specifying the part number as follows:
For example, the product with package type SOT-89, output voltage 5.0V, version A,and taping type T1 is des-
ignated as the part number "RH5RL50AA-T1".

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.
