RP155 Series
200 mA Voltage Regulator (LDO Regulator) with Alternative Dual-Voltage Level Output

Product Specifications

The RP155 is a 200-mA LDO regulator with a selectable dual-voltage level output. It provides the VSEL pin that is used to select one of two preset output voltage levels.
Excellent ripple rejection, input transient response, and load transient response make the RP155 ideal for the application for mobile communication equipment. For protection, the RP155 provides a short-current limiting circuit, a thermal shutdown circuit and an inrush current limiting circuit.
The RP155 is offered in a 5-pin WLCSP-5-P1 package which achieves the smallest possible footprint solution on boards where area is limited.

PRODUCT LONGEVITY PROGRAM

RP155 series operate PRODUCT LONGEVITY PROGRAM (ten-year supply is maintained as of January, 2016).
This program has been introduced to help customers select the most appropriate part for applications that require long life cycles.


SELECTION GUIDE

The set output voltage, the package type and the auto discharge function are user-selectable options.

Product Name   Package Quantity per Reel
RP155ZxxxB-E2-F ConsumterPLP WLCSP-5-P1 5,000
  • xxx … Specify a combination of two set output voltages (VSET1/ VSET2).
    VSET1/ VSET2 can be selected within the range of 1.6 V to 3.6 V.

* Auto-discharge function quickly lowers the output voltage to 0 V by releasing the electrical charge accumulated in the external capacitor when the chip enable signal is switched from the active mode to the standby mode.
