I plan to use two ADP7104 (3.3V) regulators to power the AVDD and IOVDD separately on an ADAU1761, is this possible? If yes are there any restrictions on power sequencing, e.g IOVDD has to come up first or vice versa? For the board reset I'd tie together both EN/UVLO pins of the regulators together.
