RP114x SERIES

300mA LDO REGULATOR

OUTLINE

NO. EA-236-160824

The RP114x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply

current, low dropout, and high ripple rejection. Each of these voltage regulator ICs 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.

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 these ICs is internally fixed.

These ICs 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 Series are excellent, thus these ICs are very suitable for

the power supply for hand-held communication equipment.

Since the packages for these ICs are DFN(PLP)1010-4, SC-88A, SOT-23-5, therefore high density mounting

of the ICs on boards is possible.
