VOLTAGE REGULATOR

FOR MIDDLE OUTPUT CURRENT

R×5RE SERIES

APPLICATION MANUAL

NO.EA-016-0006

VOLTAGE REGULATOR

FOR MIDDLE OUTPUT CURRENT

R×5RE SERIES

OUTLINE

The R×5RE Series are voltage regulator ICs with high output voltage accuracy 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, and a current limit circuit. By use of these ICs, a con-

stant voltage power supply circuit with high efficiency can be constructed because the dropout voltage and

quiescent current of these ICs are very small. Furthermore, theses ICs have a built-in current limit circuit.

The output voltage of these ICs is fixed with high accuracy.

Two types of packages, TO-92 and SOT-89 (Mini-power 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.

R×5RE

TYPICAL APPLICATION

In R×5RE 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×5RE

SERIES

*

VOUT=Vreg · (1+R2/R1) + ISS · R2

VIN

VOUT

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×5RE 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

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.

• 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 :
