High Current LDO with Low I
Q
and High PSRR
ISL9007
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 output voltage options
may be available upon request.
Features
• High performance LDO with 400mA continuous output
• Excellent transient response to large current steps
• Excellent load regulation: <0.1% voltage change across full
range of load current
• Very high PSRR: 75dB @ 1kHz
• Wide input voltage capability: 2.3V to 6.5V
• Very low quiescent current: 50µA
• Low dropout voltage: typically 200mV @ 400mA
• Low output noise: typically 30µV
RMS
@ 100µA (2.5V)
• Stable with 1µF to 10µF ceramic capacitors
• Shutdown pin turns off LDO for 1µA (max) standby current
• Soft-start to limit input current surge during enable
• Current limit and overheat protection
• ±1.8% accuracy over all operating conditions
• 8 Ld MSOP package
• -40°C to +85°C operating temperature range
• Pb-free (RoHS compliant)
Applications
• PDAs, Cell Phones and Smart Phones
• Portable Instruments, MP3 Players
• Handheld Devices, including Medical Handhelds

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347
for details on reel specifications.
2. 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.
