The RP173x Series are CMOS-based voltage regulator ICs featuring 150 mA output and low supply current of Typ.2.0μA. Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, a current limit circuit, a chip enable circuit and a Reverse Current Protection Circuit. RP173x 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 resistance to make its supply current ultra low. The RP173x 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. Since the packages for these ICs are the SOT-23-5 package, SC-88A, or DFN(PLP)1010-4 of 1mm square, high density mounting of the ICs on boards is possible.
