RP100 Series

Low Noise 0.6% Accuracy 200mA LDO Regulator

  • Consumer
  • RoHS

The RP100 Series are CMOS-based LDO regulators featuring 200mA output. RP100 features supply current as low as 18µA, which is far lower than existing lines. Due to a built-in 0.87Ω (at VSET=2.8V) on-resistor, RP100 can provide a low dropout voltage. RP100 also features an excellent line transient response, ripple rejection at 75dB, and low noise. The output voltage accuracy is as high as ± 0.6% and the temperature drift coefficient of output voltage is low at ± 30ppm/°C.
