ISL9007

Datasheet March 27, 2008

High Current LDO with Low IQ and High
PSRR

ISL9007 is a high performance LDO that delivers a
continuous 400mA of load current. It has a low standby
current and high PSRR and is stable with output capacitance
of 1µF to 10µF with an ESR of up to 200mΩ.

The ISL9007 has a very high PSRR of 75dB and output
noise less than 30µV

. When coupled with a no load

RMS

quiescent current of 50µA (typical), and 1µA (max) shutdown
current, the ISL9007 is an ideal choice for portable wireless
equipment.

The ISL9007 comes in fixed voltage options of 3.3V, 2.85V,

2.8V, and 2.5V with ±1.8% output voltage accuracy
over-temperature, line and load. 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. Add “-T” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
