ISL9005

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 1

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

less than 45

current of 50

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

ISL9005 is an ideal choice for portable wireless equipment.

Several different fixed voltage outputs are standard. Other

output voltage options for the LDO are available on request

and range from 1.3V 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.
