ISL9001A 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 output capacitance of 1µF to 10µF with ESR of up to 200mΩ. The ISL9001A has a very high PSRR of 90dB and output noise less than 30µVRMS. A reference bypass pin allows for the connection of a noise-filtering capacitor for low-noise and high-PSRR applications. When coupled with a no load quiescent current of 25µA (typical), and 0. 1µA shutdown current, the ISL9001A is an ideal choice for portable wireless equipment. The ISL9001A provides a PGOODsignal with delay time programmable through an external capacitor. Several different fixed voltage outputs are standard. Output voltage options for each LDO range from 1.5V to 3.3V. Other output voltage options may be available upon request.
