RN5RT SERIES
8V INPUT LOW SUPPLY CURRENT VOLTAGE REGULATOR
NO.EA-038-130422
OUTLINE
The RN5RT Series are CMOS-based voltage regulator ICs with high output voltage accuracy and low supply
current developed . Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier,
output voltage setting resistors and a current limit circuit. The output voltage of these ICs is fixed with high
accuracy.
The built-in Driver Transistor of low ON Resistance permits developing of low dropout CMOS type regulator as
RN5RT Series. Even if V
OUT
is shorted to GND, the current limit circuit protects the ICs from destruction.
Furthermore, these ICs have a chip enable function, so that the supply current on standby can be minimized.
Since the package for these ICs is the SOT-23-5 (Mini-mold) package, high density mounting of the ICs on
boards is possible.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field.
The functional operation at or over these absolute maximum ratings is not assured.
RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor 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 recommended operating conditions.
