RP170x SERIES

300mA 10V INPUT LDO REGULATOR

NO.EA-205-160425

1

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. 23

μA 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.
