RP171x SERIES
150mA 10V INPUT LDO REGULATOR
NO.EA-245-160324
OUTLINE
The RP171x Series are CMOS-based LDO regulators featuring 150mA output current. Because of the 10V
maximum input voltage, RP171x 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 1.2V is possible. The output voltage accuracy and temperature-drift coefficient
of output voltage of the RP171x Series are excellent.
RP171x 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 and SOT-23-5 with high power dissipation packages are available.
