ADP7104 5V out Power Good Pin to 3.3V logic

Our ADP7104ARDZ-5.0 (+12 In +5 Out) is interfaced to a common "power rail good" bus.  All other devices on this bus are pulled up to +3.3V, however this device specifies pulling up the PG pin to either the input or output voltage.  Either of these exceed our common bus voltage.

 

Will this PG pin operate OK when pulled up to less than the +5V output?
