I like the
TI/PowerTrends PT78ST105. >85%, 1.5A, no external
components. About the size of a TO220+heatsink. Very, very nice
modules.
I agree, but I'm not sure that a 1.5A rating is enough for this
application. The Micrel part is rated for 3A. It's all good--my idea of a "voltage
regulator IC" used to be a 741
op amp feeding a darlington. :)
Hey, there you go. ;) I'm a 2N3055 man, myself. You can arc weld
with those things.
