300mA 10V Input LDO Regulator for Automotive Applications
The RP170x Series are LDO regulators featuring 300mA output current that are developed with CMOS process technology. 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.
SOT-23-5 and SOT-89-5 with high power dissipation packages are available.
