RP170x Series
AEC-Q100 Grade 2 Certified
300 mA 10 V Input LDO Regulator for Automotive Applications
NO. EC-205-140224
OUTLINE
The RP170x Series are LDO regulators featuring 300 mA output current that are developed with CMOS
process technology. Because of the 10 V 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. 23
μA
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 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.
SOT-23-5 and SOT-89-5 with high power dissipation packages are available.

Auto-discharge function quickly lowers the output voltage to 0 V by releasing the electrical charge accumulated in the
external capacitor when the chip enable signal is switched from the active mode to the standby mode.

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 RATINGS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating ratings. The semiconductor devices cannot operate normally over the recommended
operating ratings, even if when they are used over such ratings by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended operating
ratings.
