LDO with Low ISUPPLY, High PSRR
ISL9001 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 an output
capacitance of 1µF to 10µF with an ESR of up to 200mΩ.
The ISL9001 has a very high PSRR of 90dB and outputs
noise less than 30µVRMS. A reference bypass pin allows
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 ISL9001 is an ideal choice for portable wireless
equipment.
The ISL9001 provides a power-good signal with delay time
programmable with an external capacitor.
Several different fixed voltage outputs are standard. Output
voltage options for each LDO range are from 1.5V to 3.3V.
Other output voltage options may be available upon request.
