ISL9001 LDO with Low ISUPPLY, High PSRR ISL9001 is a high performance Low Dropout linear regulator capable of sourcing 300mA current. It has a low standby current and high-PSRR and is stable with an output capacitance of 1µF to 10µF with an ESR of up to 200m. The ISL9001 has a very high PSRR of 90dB and outputs noise less than 30µVRMS. A reference bypass pin allows connection of a noise-filtering capacitor for low-noise and high-PSRR applications. When coupled with a no load quiescent current .
