1 / 32 page RP170x SERIES 300mA 10V INPUT LDO REGULATOR NO.EA-205-160425 1 ∗ RP170Q (SC-88A) is the discontinued product as of April, 2016. 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.
