R1180x SERIES
150mA LDO REGULATOR
NO.EA-105-111027
OUTLINE
The R1180x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low
supply current, and low ON-resistance. Each of these ICs consists of a voltage reference unit, an error amplifier,
resistor-net for voltage setting, a current limit circuit which prevents the destruction by excess current, and so on.
The output voltage of these ICs is fixed with high accuracy. B version has a chip enable pin, therefore ultra-low
consumption current standby mode can be realized with the pin.
Since the packages for these ICs are SOT-23-5 (R1180N Series), SC-82AB (R1180Q Series), and SON1612-6
(R1180D Series), therefore 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.
