the LM338 is, after all, a voltage reference, error amplifier and pass
element with current limiting -- you can raise the adjust pin above ground
with a zener to make a higher voltage regulator -- but you have to remember
to bias the zener since the adjust pin current may not be enough to do the
trick.
