I'm not sure if he's referring to the same idea.
Maybe or nobe, linked is just one (easy) way.
BTW, the LM317 (1.5A) comes in various packages.
The TO220 version is the "T" suffix, so: LM317T.
I did'nt realize yesterday, the LM350 (3A) comes
in both TO3 (LM350K) and TO220 (LM350T) packages.
Simultaneous use of 3 LM317's, 2 LM350's, 1 LM317
and 1 LM350, or any combination you can think of,
won't jeopardize your "interest in the fact that
only one set of peripheral components are needed".

Jan
