ISL9001A

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 200m

Ω.

The ISL9001A has a very high PSRR of 90dB and output

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.

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.
