No it doesn't, but chips are available with a regulator built in, that do.
Basically if it's a 'standard' DX4-100, it requires 3.3v, if it is
marketted as an 'overdrive' chip, it may well have the 3.3v regulator,
and will be designed to run at 5v, not 3.3.
There were also some 5vDX4's from AMD in the early days, but not recently.

Hope this helps
