Hello. The cyclone II handbook says to connect VCCA to a 1,2V supply. OK, but to choose the regulator I need to know the min and max voltages? Does anybody know it? Thanks

Simply assume the same tolerances as for VCCINT (1.15 - 1.25). It's generally assumed that both are powered from the same supply, with some additional filtering for VCCA.
