I did a little searching on National's web site tonight and I found
that this part is TO-202 which is the same size as a normal 7805
regulator (overkill for most calculator applications)
(If I'm wrong... and it wouldn't be the first time, believe me,
disregard that... its late and my head went into APD hours ago)
I needed a low dropout TO-92 regulator for the Extender uP (I am
going to drop the worthless 78L05) and I found National's LM2931
series. These are in full production, and look like very nice
regulators. They can handle 100 mA of current too!
I love ordering samples... its like being a kid in a free candy
store. ;-)
