RP100x Series
Low Supply Current 200mA LDO
The RP100x Series are CMOS-based LDO regulators featuring 200mA output.
Various basic performances of the RP Series have been improved by adopting a new manufacturing process. RP100x features supply
current as low as 18μA, which is far lower than existing lines. Due to a built-in 0.87Ω (at V
OUT
=2.8V) on-resistor, RP100x can provide a
low dropout voltage. RP100x 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.
