RP170x Series AEC-Q100 Compliant 300 mA 10 V Input LDO Regulator for Automotive Applications No. EC-205-190107 OUTLINE The RP170x is an LDO regulator featuring 300 mA output current. Having the 10 V maximum input voltage, the RP170x 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 1.2 V is possible. The output voltage accuracy and temperature-drift coefficient of output voltage of the RP170x is 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.
