What to do with unused regulators

Hello everybody!

 

I am designing a board where the ADuCM350 will never connect to an USB host or to a LCD.

 

If I understand the HRM right, I can connect VLCD_VDD to VCCM and leave VLCD_13, _23, _FLY1 and _FLY2 floating.

 

The situation with the USB regulator is less clear. VBUS can of course be left floating (as if the cable is disconnected). What to do with VUSB? Can i leave it floating, too?

 

Regards,

Enrico
