The RP173 Series are CMOS-based LDO regulators featuring 150mA output and low supply current of Typ. 2.0µA. RP173 Series are suitable for the power source such as the equipment being in the standby-mode. A version with CE input pin has reduced CE pull-up resistor to make its supply current ultra low.
The RP173 Series have Max.11V* Input voltage and are applicable to the portable communication equipment that require the 2-cell Li-ion battery. Also they are applicable to the non-portable communication equipments. As this series includes Reverse Current Protection Circuit, there is little leakage current, if it's used as back-up circuit. SOT-23-5 and SC-88A packages, a 1mm square DFN(PLP)1010-4 package are available.
