The RP101x Series are CMOS-based LDO regulators featuring 300mA output. RP101x 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 VOUT=2.8V) , RP101x provides a low dropout voltage. RP101x 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 temperature drift coefficient of the output voltage is as low as ± 30ppm/°C.
The document describes the Ricoh RP101x Series, which are CMOS-based Low Dropout (LDO) regulators featuring a 300mA output current. These devices offer a supply current as low as 18µA and an output voltage accuracy of +0.6%. Key features include excellent line transient response, 75dB ripple rejection at 1kHz, and a temperature drift coefficient of the output voltage as low as +30ppm/°C.
