Barrie, that's a pretty extreme voltage difference. You should not be having this problem. I assume there is a basic mistake somewhere. Do you have the in-out pin connections correct? Do you have the ground pin grounded?
You can get data sheets for most regulators from the manufacturers or from Digi-Key. At Digi-Key you do a part search, select a part number, and then click on the highlighted part number in the Technical/Catalog Information field, click on the datasheet, and you get a datasheet in pdf form.
