RP170x SERIES
300mA 10V INPUT LDO REGULATOR
NO.EA-205-160425
OUTLINE
The RP170x Series are CMOS-based LDO regulators featuring 300mA output current. Because of the 10V
maximum input voltage, RP170x can be used in 2 cell lithium-ion battery powered portable appliances and
besides a portable equipment. The supply current is Typ. 23μA though an excellent response characteristics.
The output voltage range from 1.2V is possible. The output voltage accuracy and temperature-drift coefficient
of output voltage of the RP170x Series are excellent.
RP170x has a fold-back protection circuit and a thermal shutdown circuit. Moreover, a standby mode with ultra
low supply current can be realized with the chip enable function.
SC-88A, SOT-23-5 and SOT-89-5 with high power dissipation packages are available.

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.
