R1182x SERIES
Non-promotion
Seamless Low Supply Current 150mA LDO REGULATOR
NO.EA-133-130416
OUTLINE
The R1182x Series are CMOS-based positive voltage regulator ICs with high output voltage accuracy and low
supply current. 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.
The R1182x Series has low dropout voltage caused by built in low on resistance transistor. Further, the
consumption current of IC itself is Typ. 3.0μA at no load, at the same time, compared with the conventional low
supply current regulator, transient response is improved in all the load range by our original seamless
technology.
Since the packages for these ICs are SOT-23-5 and ultra small DFN(PLP)1616-6, 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.
