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×5RL30A, VIN=5.0V)
• Small Dropout Voltage .....................................TYP. 30mV (R×5RL50A, IOUT=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)

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.
Insert Capacitors C1 and C2 with the capacitance of
0.1µF to 2.0µF between Input/Output Pins and GND Pin
with minimum wiring.
As shown in the circuit diagram, a dual power sup-
ply circuit can be constructed by using two R×5RL
Series.
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.

The output voltage can be obtained by the follow-
ing formula :
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 kΩand 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.

APPLICATION CIRCUITS

• CURRENT BOOST CIRCUIT
Output current of 60mA or more can be obtained by
the current boost circuit constructed as shown in this cir-
cuit diagram.
• CURRENT BOOST CIRCUIT WITH OVERCURRENT LIMIT CIRCUIT
A circuit for protecting Tr.1 from the destruction
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 :
IOUT Vbe2/R2
• CURRENT SOURCE
A current source with the structure as shown in this
circuit diagram can be used. Output Current IOUT is
obtained as follows :
IOUT= Vreg /R + ISS
Take care that Output Current IOUT does not exceed
its allowable current.
