*RP173Q(SC-88A) is the non-promotion product as of March 2020. RP173x Series 11 V Input 150 mA LDO No. EA-256-200430 OUTLINE The RP173x is a voltage regulator featuring 150 mA output and low supply current of Typ. 2.0 A. 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.

RP173x No. EA-256-200430 SELECTION GUIDE (1) The output voltage, the auto-discharge function , and the package for the ICs are user-selectable options. Selection Guide Product Name Package Quantity per Reel Pb Free Halogen Free RP173Kxx1-TR DFN(PLP)1010-4 10,000 pcs Yes Yes RP173Qxx2-TR-FE SC-88A 3,000 pcs Yes Yes SOT-23-5 3,000 pcs Yes Yes RP173Nxx1-TR-FE xx : The output voltage can be designated in the range of 1.2 V (12) to 5.5 V (55) in 0.1 V step. : The auto discharge function at off state are options as follows. (A) active, without auto discharge function at off state (Pull-up resistance is not built-in) (B) active, without auto discharge function at off state (D) active, with auto discharge function at off state (1) Auto-discharge function quickly lowers the output voltage to 0 V, when the chip enable signal is switched from the active mode to the standby mode, by releasing the electrical charge accumulated in the external capacitor. 2
