    My Technos water purifier/ionizer refuses to turn itself off. After
    inspecting I've found a stuck closed voltage regulator. I'm trying to
    locate a compatible regulator. Where can I find a voltage regulator
    replacement for this one?

    FW0128 FQP W 50N06

    This is not a voltage regulator but a N channel MOSFET. Datasheet at

    FW0128 is probably some production date code. The 'W' seems to be the
    Motorola logo. So the full part number is FQP50N06.

    Hope this helps,
  3. $1.36 at Mouser.

    Thanks for searching. And thanks for the correction, Jeroen, which
    allowed me to replace it with a Motorolla N-Channel (MTW 14N50E 01,
    attached to a larger heat-sink) I'd salvaged from a computer monitor. I
    don't believe that salvaging a part from a computer monitor is
    professional but it seems to solve the problem quiet fine.
