RP170x Series
AEC-Q100 Compliant
300 mA 10 V Input LDO Regulator for Automotive Applications
No. EC-205-190107
OUTLINE
The RP170x is an LDO regulator featuring 300 mA output current. Having the 10 V maximum input voltage,
the RP170x can be used in 2 cell lithium-ion battery powered portable appliances and besides a portable
equipment. The supply current is Typ. 23
A
though an excellent response characteristics. The output
voltage range from 1.2 V is possible. The output voltage accuracy and temperature-drift coefficient of output
voltage of the RP170x is 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.
SOT-23-5 and SOT-89-5 with high power dissipation packages are available.

RECOMMENDED OPERATING CONDITIONS
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.
