ISL9005A
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 200m
Ω
.
The ISL9005A has a high PSRR of 75dB and output noise
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. Other
output voltage options for the LDO may be available on
request and range from 1.35V to 3.6V.

NOTES:
1. Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are 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. For other output voltages, contact Intersil Marketing.
