Hooking up L78L33 3v3 regulator from 9V

See datasheet L78L33[1].

BOTTOM VIEW
 _________
 \ 1 2 3 /
  \_____/

1 = V_OUT
2 = GND
3 = V_IN

These are from the test circuit.  Not sure if necessary:
C_IN = 0.33uF
C_OUT = 0.100uF

I' just put 2 1uF elcos on either side.

Plugged it in wrong first (pic says bottom view!).  It started
smelling, got pretty hot.  Still works after turning it around.
