If the regulator is oscillating, it will usually get pretty hot real fast. The problem may (or may not) be a result of this. I would look at it with a 'scope. I have found that the regulators don't regulate running open circuit. Some type of resistive load could be substituted to cause around 100mA or so of current to flow and then, try measuring the output. I don't have all of the answers but I have run into this problem on some of my home projects. Barry
