OUTLINE

The RP114x is a CMOS-based voltage regulator IC with high output voltage accuracy, low supply current, low

dropout, and high ripple rejection. This IC consists of a voltage reference unit, an error amplifier, resistors for

setting output voltage, a short current limit circuit, a chip enable circuit, and so on. The RP114x features a

minimum input voltage from 1.4V and the output voltage, which can be set from 0.8V to 3.6V (in 0.1V step).

The output voltage of this IC is internally fixed. This IC perform with low dropout voltage due to built-in transistor

with low ON resistance. Low supply current and a chip enable function prolong the battery life of each system.

The ripple rejection, line transient response and load transient response of the RP114x is excellent, thus this

IC is very suitable for the power supply for hand-held communication equipment. Since the packages for

this IC are DFN(

PL)1010-4、DFN(PL)1010-4B、SC-88A、SOT-23-5, therefore high density mounting of the

IC on boards is possible.
