Hey! Something that I can contribute to on this list!  I've been asking
questions up to now but this is something I can pass along some information
on - :)

Try the LM2936Z-5.0  It's a TO-92 - same pin-out as the L05 but only sips
about  15uA quiescent current - I'm using them in a 9V thing I'm building
and they work fine, with two slight downside issues -

1) They are about 3-5 times more expensive than the 'L05  I have seen them
at up to 3 bucks a pop.

2) They require a 10uF cap on the output to prevent oscillations - I've got
this "rank" looking electrolytic - it's bigger than the regulator!

Hope this helps.

Lewis
