one of the switching regulators that can be had in TO-220 packages.
Basically the same appearance as the veneered and generated 7805, but
far more efficient.
My favorite one of those, the PowerTrends/TI PT78ST105, doesn't
look much like a TO-220, but it'll mount in that footprint. I sure
do like those. Instant efficiency upgrade!
