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 1碌F to 10碌F with an ESR of up to 200m鈩?
The ISL9007 has a very high PSRR of 75dB and output
noise less than 30碌V
RMS
. When coupled with a no load
quiescent current of 50碌A(chǔ) (typical), and 1碌A(chǔ) (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 鹵1.8% output voltage accuracy over
temperature, line and load. Other voltage options are
available on request.
Features
鈥?High performance LDO with 400mA continuous output
鈥?Excellent transient response to large current steps
鈥?Excellent load regulation: <0.1% voltage change across
full range of load current
鈥?Very high PSRR: 75dB @ 1kHz
鈥?Wide input voltage capability: 2.3V -6.5V
鈥?Very low quiescent current: 50碌A(chǔ)
