RP155Z Series

200 mA LDO Regulator with Alternative Dual-Voltage Level Output

NO.EA-334-160126

OUTLINE

The RP155Z 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 RP155Z ideal for

the application for mobile communication equipment.

For protection, the RP155Z provides a short-current limiting circuit, a thermal shutdown circuit and an inrush

current limiting circuit.

The RP155Z is offered in al 5-pin WLCSP-5-P1 package which achieves the smallest possible footprint solution

on boards where area is limited.
