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 200m.

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.

NOTES:

1. These Intersil Pb-free plastic packaged products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte

tin plate PLUS ANNEAL - e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations.

Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC

J STD-020.

2. Please refer to TB347 for details on reel specifications.

3. For other output voltages, contact Intersil Marketing.
