The LM317KTE is like the D2-pak, but only 2mm thick and still able to supply over 1.5 amps, which is why I want some. Digi-key have them, but not in stock, and to get a cost effective price I'd have to buy 500 of them!
It doesn't help that they're not recommended for new designs, are discontinued by Texas Instruments. Or does it? Maybe someone has some and might sell me some? Payment would ideally be made by Paypal. Quantity wanted can be variable, so long as the quantity, nor the cost, is too high.
An alternative I can use is a smaller D-pak device that will supply 1.5 amps or more. I don't think there is one, but I could easily be wrong. The SOT-223 types won't do, as I can't mount them to a chassis or panel.
