Re: IC Marking
These days when I keep them in a bag and mark the bag for type. For singles I use a Sharpie pen and mark the type on the TAB(e;g 7805 or +05with the current suffix) when I get them.
Helps if you have a mix of both + and - regulators. As + and - terminal regulators have differing pinouts, you could also mark the tab with +/-05( current suffix) and mark the common with black ink at the top.
For a quick voltage check, I use an old Panasonic 4 pin connector with wires connected to the socket and a meter on the output. A 78/79 device plugs nicely into this and it's quick and easy to check the device.
