ISL9005A
FN6452.1
LDO with Low I_SUPPLY, High PSRR
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 45µV_RMS. 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.
