ISL9007
FN9218.0
High Current LDO with Low I_Q 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_RMS. When coupled with a no load
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 voltage options are
available on request.

NOTES:
1. For other output voltages, contact Intersil Marketing.
2. 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.
