RP100x Series
Low Noise 0.6% Accuracy 200mA LDO
No.EK-140-121001 CMOS LDO Regulator
The RP100x Series are CMOS-b ased LDO regul ators featuring 200m A output. RP100x fea tures suppl y current as low as 18μA, whic h
is far lower than existing lines. Due to a bui lt-in 0.87Ω (at VSET=2.8V) on-resist or, RP100x can provide a low dropout voltage. RP100x
also features an excellent line transient respon se, ripple rejection at 75dB, and low noise. The outpu t voltage accuracy is as high a s
± 0.6% and the temperature drift coefficient of output voltage is low at ± 30ppm/°C.
