ISL9005A 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 ISL9005A has a high PSRR of 75dB and an output

noise of less than 45μVRMS. When coupled with a no load

quiescent current of 50μA, (typical) and 0.1μA shutdown

current, the ISL9005A is an ideal choice for portable wireless

equipment.

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.
