TMDSCNCD28388D: Power Sequencing on startup

Pablo Slavkin
Prodigy 220 points

Part Number: TMDSCNCD28388D

After reading the power sequencing requirements on the datasheet that said :

I'm thinking to connect 1.2v regulator (to supply VDD) after 3v3 (VDDIO and VDDA supply) and connect like in these schema.

In these approach I'll be sure that VDD will always be less than VDDIO.

Do you think it's a good idea (apart from power energy efficiency, just in concept)

Thanks!
