RP173x Series
11 V Input 150 mA LDO
No. EA-256-171101
OUTLINE
The RP173x is a voltage regulator featuring 150 mA output and low supply current of Typ. 2.0
µA.
It 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 is suitable for the power source such as the
equipment being in the standby-mode. The A version with CE input pin has reduced CE pull-up resistance to
make its supply current ultra low.
The RP173x has Max.11 V Input voltage and is applicable to the portable communication equipment that
requires the 2-cell Li-ion battery. Also it is applicable to the non-portable communication equipments. As the
RP173x includes Reverse Current Protection Circuit, there is little leakage current, if it is used as back-up
circuit.
Packages are available in SOT-23-5, SC-88A, and 1-mm square DFN(PLP)1010-4 packages. High density
mounting of the ICs on boards is possible.
