Hmm, I have used some switcher chips from Linear technology, and with tiny 
low profile inductors from Coilcraft, would easily match that 7805 
equivalent that you pictured. With A size case tantalums and very small SMD 
resistors, you really cannot get much smaller with anything. Even using 1206 
resistors it can be quite small.
