RP170 Datasheet, PDF (1/32 Pages) RICOH electronics devices division – Supply Current Typ. 23uA

∗ RP170Q (SC-88A) is the discontinued product as of April, 2016.
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.
