[Q] Module Power Consumption

2003-04-11 by Tentochi

Oops!  Sorry for that previous post.  Laptop keyboards and myself don't
get along too well.

Anyway, do modules pull more when then are not being used?  For
example, is the '300 pulling 60mA all of the time on both power rails
or is it only a theoretical maximum when all inputs and outputs are
being utilized?  I am sure the answer is a bit more complex than my
simple question.

In general, what type of modules cause the draw on each rail to not be
equal?

Does having unequal amounts of power being drawn off of each rail
affect the PSU or quality of power on the rails themselves?

Thanks!
Shemp
