The 555 definitely will source 200 milliamps, but I am not
sure for how long.  I once connected a #47 pilot lamp to the output of
a 555 and drove it for a minute or less and I almost left the first
layer of skin from one of my fingers baked to its surface when I
touched it to see how hot it was.  I seem to also recall that it
behaved strangely with that much of a load on it.  Basically, the 555
is a lot happier if you don't push things that hard.
