ISL9005

LDO with Low ISUPPLY, High PSRR

DATASHEET

ISL9005 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

.

The ISL9005 has a high PSRR of 75dB and output noise

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

ISL9005 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.
