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 200m
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. Other
output voltage options for the LDO are available on request
and range from 1.3V to 3.6V.

... Smart thermal shutdown protects the device against overheating. Power Control The ISL9001A has an enable pin (EN) to control power to the LDO output. When EN is low, the device is in shutdown mode. During this condition, all on-chip circuits are off, and the device draws minimum current, typically less than 0.1μ ...
