ISL9000 Description
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 200m. 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.
