LDO with Low I, High PSRR

Support is limited to customers who have already adopted these products.

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 200mΩ. 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 of 25µA (typical), and 0. 1µA shutdown current, the ISL9001 is an ideal choice for portable wireless equipment. The ISL9001 provides a power-good signal with delay time programmable with an external capacitor. Several different fixed voltage outputs are standard. Output voltage options for each LDO range are from 1. 5V to 3. 3V. Other output voltage options may be available upon request.
