RICOH RP114x SERIES 300mA LDO REGULATOR datasheet user manual
Summary
The RP114x Series are highly reliable CMOS-based Low Dropout Voltage Regulator ICs, engineered for power-sensitive applications like portable communication equipment and battery-powered devices. Featuring low supply current (0.1μA standby), excellent ripple rejection, and adjustable output voltage (0.8V to 3.6V), these regulators ensure stable power delivery even when the main source is changing or dropping significantly. This documentation provides a comprehensive overview of features, detailed operating ranges, selection guides for various packages (DFN, SC-88A, SOT-23-5), and precise pin configurations to help engineers efficiently integrate stable power sources into their designs.

RP114x SERIES
300m A LDO REGULATOR
NO. EA-236-120613
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.
