RP112 Series
Low Noise 150mA LDO Regulator
The RP112 Series are CMOS-based LDO regulators featuring 150mA output current. The RP112 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. RP112 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.
