Here in Silicon Valley, Fry's Electronics sometimes sells them       for under a dollar. This may not work reliably if your unregulated supply is       over 18V, but should        work fine if it is 15V or less.       >              Thankyouthankyouthankyou! I have a function generator that at 12V will       bake the 78L05 TO-92 cased regulator; the switchmode .5A unit should       work a treat in its place so I don't have to have a second PSU just for       it, when working on speedometers for my cars!              RwP              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
