RP101 Series
Low Noise 0.6% Accuracy 300mA LDO Regulator

Download Datasheet

  • Description

    The RP101 Series are CMOS-based LDO regulators featuring 300mA output. RP101 has the supply current as low as 18µA, which is far lower than current products. Due to a built-in transistor with low on-resistance of 0.87Ω (at VSET=2.8V) , RP101 provides a low dropout voltage. RP101 also has an excellent line transient response, 75dB ripple rejection, and low noise. The output voltage accuracy has been improved to ± 0.6% and the temparature drift coefficient of the output voltage is as low as ± 30ppm/°C.
