LDO with Low I
ISL9001A is a high performance Low Dropout linear
regulator capable of sourcing 300mA current. It has a low
standby current and high-PSRR and is stable with output
capacitance of 1µF to 10µF with ESR of up to 200mΩ.
The ISL9001A has a very high PSRR of 90dB and output
noise less than 30µV
connection of a noise-filtering capacitor for low-noise and
high-PSRR applications. When coupled with a no load
quiescent current of 25µA (typical), and 0.1µA shutdown
current, the ISL9001A is an ideal choice for portable wireless
equipment.
The ISL9001A provides a P
programmable through an external capacitor.
Several different fixed voltage outputs are standard. Output
voltage options for each LDO range from 1.5V to 3.3V. Other
output voltage options may be available upon request.
