RP114x SERIES
300mA LDO REGULATOR
NO. EA-236-160824
OUTLINE
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.
