21 March 2013 Question by: Rapid Customer | Product code: 47-3298
Q. Which pin is the case of the L7912 (or L7812) connected to? If I mount one of each on the same heatsink, will I need insulating washers?
A. Hi Berni. Thank you for your question. This device is not shown as having any pins connected to the case at all but to be extra safe you could also use a mica washer for each to further insulate them.
