DATASHEET ISL9000A Dual LDO with Low Noise, Very High PSRR and Low IQ FN6391 Rev 3.00 October 15, 2015 ISL9000A 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 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 CP
