RP130x Series
Low Noise 150mA LDO
The RP130x Series are CMOS-based LDO regulators featuring 150mA output. The RP130x features an excellent line transient
response, a high ripple rejection at 80dB, and ultra low noise. The polarity of the CE pin can be selected. The version with
auto-discharge function is also available. Compared to existing high-speed lines, the RP130x provides low supply current at Typ.
38μA. The series covers a wide voltage range, including the input voltage range of 1.7V to 6.5V and the output voltage range of 1.2V to
5.0V. Ceramic capacitors can be used.
