ISL9000
FN9217.0
Dual LDO with Low Noise, Very High
PSRR, and Low IQ
ISL9000 is a high performance dual LDO capable of
sourcing 300mA current from each output. It has a low
standby current and very high PSRR and is stable with
output capacitance of 1µF to 10µF with ESR of up to 200mΩ.
The device integrates an individual Power-On-Reset (POR)
function for each output. The POR delay for VO2 can be
externally programmed by connecting a timing capacitor to
the CPOR pin. The POR delay for VO1 is internally fixed at
approximately 2ms. A reference bypass pin is also provided
for connecting a noise filtering capacitor for low noise and
high-PSRR applications.
The quiescent current is typically only 42µA with both LDO’s
enabled and active. Separate enable pins control each
individual LDO output. When both enable pins are low, the
device is in shutdown, typically drawing less than 0.1µA.
Several combinations of voltage outputs are standard.
Others are available on request. Output voltage options for
each LDO range from 1.2V to 3.6V.
