with the numbers available on minimum and maximum voltage of the output of the regulator a list can be made to check whether all the ICs are getting supply voltage which is with in their standard operating voltages.
To calculate maximum voltage across the IC supply pin, assume current to be the least and assume resistance of ferrites and zero ohm resistors in series with the supply which suits between regulator output and IC supply as zero.
To calculate minimum voltage assume maximum current into IC and assume maximum resistance at extend temperature for both series zero ohm resistor and ferrites.
maximum voltage will be maximum voltage output of switching regulator.
minimum voltage will be supply voltage minimum minus drop across ferrite bead and series zero in jumpers and series resistance of connectors.
