FT2232H current consumption at 3.3V calculation
As mentioned in the comments, probably 100ma.

ps: never rely on the parameters provided by digikey/fernell/etc, theyre just a rough guideline to help you search. Many parts have wildly incorrect listed parameters, or just dont have any.

edit: as chris says, remember that these are typical figures. They will vary as the chip does its stuff. Notice that no maximum current is given for the core, but we can infer what the maxmimum could be by assuming that the regulator will always be able to handle it, meaning that it must be &lt;90ma (150-60). If the core does require more than this in normal usage, it would probably malfunction often, and no-one would buy it.
