I need to design a compression spring to diplace 50 mm for each kilo of load and an overall displacement of 300 mm. Any help would be well apreciated.

I've got an LM7812 conected to a 24v battery supply with a load of 63mA max. The device has failed on me twice dispite trying heatsinks (which shouldn't be necessary at such a low load).It's used on a relay circuit board for dc motor starting, so I suspect it might be a surge problem but I can't...
