VOLTAGE REGULATOR
FOR MIDDLE OUTPUT CURRENT
NO. EA-016-100120
Rx5RE SERIES
OUTLINE
The Rx5RE Series are CMOS-based voltage regulator ICs with high output voltage accuracy 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, 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.

TYPICAL APPLICATION
In Rx5RE 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

Rx5RE
*
VIN
VOUT
VOUT=Vreg · (1+R2/R1) + ISS · R2
SERIES
Since the quiescent current of Rx5RE 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 Rx5RE 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

ply circuit can be constructed by using two Rx5RE
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.

When the voltage reduction caused by the current (
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.

as follows :
