I would not use tants. When these die due to a fault or whatever, they
tend to go short. If you conect these directly across your rails, then
its goodbye regulator and hello to burnt pcbs. Ordinary electrolytics
(elec's...?) are fine for this I would have thought, especially if you
put a low value cap in parallel with it.
