OUTLINE
The RP112x is a voltage regulator (LDO) with high output voltage accuracy, low-supply current, low On-
resistance transistor, low noise output voltage and high ripple rejection. Each IC 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 80 dB at f = 1 kHz, 75 dB at f = 10
kHz and 65 dB at f = 100 kHz. The Output Noise is also as low as Typ. 10 μVrms. 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 1-mm square DFN(PLP)1010-
4 package are available.

TECHNICAL NOTES
Phase Compensation
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, use a 1.0 F or more capacitor C2.
In case of using a tantalum capacitor, the output may be unstable due to inappropriate ESR. Therefore, the
full range of operating conditions for the capacitor in the application should be considered.
PCB Layout
The high impedances of VDD and GND could be a reason for the noise pickup and unstable operation.
Therefore, it is imperative that the impedances of VDD and GND be the lowest possible. Also, place a 1.0 µF
or more capacitor (C1) between VDD pin and GND pin as close as possible to each other.
As for C2 output capacitor that is used for phase compensation, place it between VOUT pin and GND as close
as possible to each other (Refer to TYPICAL APPLICATIONS).
