ISL9005
FN9234.2
LDO with Low ISUPPLY, High PSRR
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 200mΩ.
The ISL9005 has a high PSRR of 75dB and output noise
less than 45µVRMS. When coupled with a no load quiescent
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.

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.
