RP112x SERIES
Low Noise 150mA LDO REGULATOR
NO.EA-258-111020
OUTLINE
The RP112x Series are CMOS-based voltage regulator (LDO) ICs, which have been developed using the
CMOS process technology, with high output voltage accuracy, low-supply current, low On-resistance transistor,
low noise output voltage and high ripple rejection. Each of the ICs is composed of the followings: a voltage
reference unit, an error amplifier, a resistor-net for output voltage setting, a current limit circuit, and a chip enable
circuit.
The RP112x features ultra low noise and its Ripple Rejection is as low as 80dB at f=1kHz, 75dB at f=10kHz
and 65dB at f=100kHz. The Output Noise is also as low as Typ. 10μVrms. It is kept the low level at any Output
Voltage. RP112x is suitable for the power source for the portable music player and RF module that demands for
higher level of noise reduction. SOT-23-5 and SC-88A packages, a 1mm square DFN(PLP)1010-4 package are
available.
