VOLTAGE REGULATOR  
NO. EA-022-0204  
Rx5RL SERIES  
OUTLINE  
The Rx5RL Series are CMOS-based voltage regulator ICs with high accuracy output voltage 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. 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.

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 Rx5RL 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  
Rx5RL  
*
VIN  
VOUT  
VOUT=Vreg · (1+R2ꢀR1) + ISS R · 2  
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 kand therefore the sup-  
ply current of “Voltage Boost Circuit” itself can be  
reduced.  
+
GND

Furthermore, since Rx5RL 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 Rx5RL  
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.

caused by output short-circuit or overcurrent is shown in  
this circuit diagram.

IOUT  
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 :
