Assuming the MMIC inside the can is as stated on the label, there won't be a voltage reg inside the can.

The SPF5189Z is rated to run directly off 5V.

It definitely sounds like some kind of fault.

Once you get the replacement, I would remove the can and see if you can find anything faulty inside (assuming you don't have to return the faulty one).
