Sorry, but the drawing you provided is totally irrelevant to the problem.  You were requested for actual as-built circuit, not a drawing from the vendor data sheet  -  which, by the way calls for a 0.1microfarad on the output as well as a 0.33 on the input, both of which should be as close as possible to the regulator pins.  Have you considered the possibility that your regulator may be defective.

Yes I have tried other 7805s ther behaved the same...
Only when I use the small 7805 (TO- 92) there is no problem...
