Rx5RE SERIES
VOLTAGE REGULATOR
OUTLINE
NO. EA-016-120404
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 constant 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 (Discontinued) and SOT-89 (Mini-power Mold) (Non-promoon) are available.
FEATURES
• Supply Current.............................................................Typ. 1.1μA (VOUT=30V, VIN=5.0V)

• Output Current .............................................................Typ. 120mA 5.0V)
• Input Voltage Range ....................................................Max. 10.0V
• Output Voltage Range..................................................2.0V t6.0V (0.1V steps)
(Fr othevoltages, please refer to MARK INFORMATIONS.)
• Output Voltage Accuracy........................................2.5%
• Temperature-Drift Coefficient of Output Voltage...p. ± 100ppm/°C
• Line Regulation...........................................................Typ. 0.1%/V
• Packages ...............................................................SOT-89 (Mini-power Mold) (Non-promotion),
TO-92 (Discontinued)
APPLICATIONS
• Power source for batter-powered equipment
• Power source for eras, video instruments such as camcorders, VCRs, and hand- held communication
equipment
• Precon voltage references

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute um ratings may cause the
permanent damages and may degrade the life time and safety for both dand system using the device
in the field.
The functional operation at or over these absolute maximum ratings is not assured.
RECOMMENDED OPERATING CONDIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment should be desigat the mounted semiconductor devices operate within the
recommended operating conditions. The miconductor devices cannot operate normally over the
recommended operating conditions, even if when they are used over such conditions by momentary
electronic noise or surge. And the semiconductor devices may receive serious damage when they continue
to operate over the recommeded operating conditions.

Rx5RL
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.

Since the quiesrrent of Rx5RE Series is so
small that the resistances of R1 and R2 can be set as
large as everal hundreds kΩ and therefore the sup-

Furthermore, since Rx5RL Series are operated by
a constant voltage, the supply current of “Voltage

input voltage.

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.
