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 200m Ω .
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
