TYPICAL APPLICATION
In R
×
5RE Series, a constant voltage can be obtained
without using Capacitors C1 and C2. However, when the
wire connected to V
IN
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.
The output voltage can be obtained by the follow-
ing formula :
V
OUT
=Vre*
SS
· R2
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 k
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.

×
5RE Series.
As shown in the circuit diagram, a dual power sup-
ply circuit can be constructed by using two R
×
5RE
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 I
SS
of IC1, Resistor R is unnecessary. Diode D is
a protection diode for the case where V
OUT
2
becomes larger than V
OUT
1.
