RP170 Series
10V Input 300mA LDO Regulator
The RP170 Series are CMOS-based LDO regulators featuring 300mA output current. Due to the 10V maximum input voltage, RP170 can be used for 2 cell lithium-ion battery powered portable appliances and home appliances. RP170 has a fold-back protection circuit, a thermal shutdown circuit and a constant slope circuit. SOT-23-5 and SOT-89-5 with high power dissipation packages are available. This product for industrial applications are characterized to -50°C, and operates in a wide temperature range from low temperature to high temperature.
