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 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

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.

Insert Capacitors C1 and C2 with the capacitance of

0.1µF to 2.0µF between Input/Output Pins and GND Pin

with minimum wiring.

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.

GND

ISS

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.

• DUAL POWER SUPPLY CIRCUIT

As shown in the circuit diagram, a dual power sup-

ply circuit can be constructed by using two R×5RL

Series.

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.

When the voltage reduction caused by the current ( aa

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 :

VIN

VOUT

R×5RL

SERIES

VIN

VOUT

GND

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

VIN

VOUT

R×5RL

SERIES

VIN

IOUT= Vreg /R + ISS

GND

ISS

Take care that Output Current IOUT does not exceed

its allowable current.

1) Vreg : Set Output Voltage of R×5RL Series.
