2) the pinout match the circuit board. For example, if you look at the board, you'll see the 7805? regulator has the GND as the center pin, whereas the 3.3V regulator has pin 1 and the GND. Some 12V and 5V regulators have different IN, OUT, and GND pin connections. Bad things happen if you put the wrong pin placements in the board, even if the amperage and voltage are correct.

Oops, yup, missed that little "-".? Probably searching wrong on Digikey, but not finding a 7805 that is 1.5A when searching for "LM7805CT/NOPB-ND" .? Perhaps I need to go somewhere else?
