RP173x SERIES

11V Input 150mA LDO

NO.EA-256-111020

OUTLINE

The RP173x Series are CMOS-based voltage regulator ICs featuring 150 mA output and low supply current of

Typ.2.0

μA. 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.
