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 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.
FEATURES
• Ultra-low Quiescent Current
...........................
TYP. 1.1µA (R×5RL30A, VIN=5.0V)
TYP. 30mV (R×5RL50A, IOUT=1mA)
.....................................
• Small Dropout Voltage
...............
• 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)
APPLICATIONS
• Power source for battery-powered equipment.

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.

TYPICAL APPLICATION
In R×5RL Series, a constant voltage can be obtained
without using Capacitors C1 and C2. However, when the
wire connected to Vin is long, use Capacitor C1. Output
noise can be reduced by using Capacitor C2.

APPLICATION CIRCUITS
• VOLTAGE BOOST CIRCUIT
The output voltage can be obtained by the follow-
ing formula :

VIN
VOUT
R×5RL
SERIES
*
VIN
VOUT
VOUT=Vreg · (1+R2/R1) + ISS R · 2
Since the quiescent current of R×5RE Series is so
small that the resistances of R1 and R2 can be set as
large as several hundreds kΩ and therefore the sup-
ply current of “Voltage Boost Circuit” itself can be
reduced.

Furthermore, since R×5RL Series are operated by
a constant voltage, the supply current of “Voltage
Boost Circuit” is not substantially affected by the
input voltage.

This circuit diagram shows a dual power supply
circuit with an output of 3V and an output of 5V.
When the minimum output current of IC2 is larger
than ISS of IC1, Resistor R is unnecessary. Diode D is
a protection diode for the case where VOUT2 becomes
larger than VOUT1.

caused by output short-circuit or overcurrent is shown in
this circuit diagram.

When the voltage reduction caused by the current ( aa
IOUT) which flows through R2 reaches Vbe2 of Tr.2 by
additionally providing the current boost circuit with Tr.2
and R2, Tr.2 is turned ON and the base current of Tr.1 is
increased, so that the output current is limited.
Current limit of Overcurrent Limit Circuit is obtained
as follows :
