Hi I am trying to identify an active SMD semi device. Its in what appears to be a SOT223 package (though the actual case is larger than the spec at 4.4mm x 2.5mm). So its like transistors with 3 legs extending on one side and a ground or thermal contact on the other. The only markings on the case is UL25. Its fitted to a Panasonic 12v auto DVD player. Any help greatfully received.
