Change current output of PSU

[nikos0608]

Hi, i found a circuit that is easy to make but i want to modify it a bit...
The circuit is based on L200 voltage and current regulator.
So, like this i can get maximum 2A current in output...
How can i get 5A output?
I know that i have to get another transformer, higher current diodes and a bigger capacitor but how about the L200?
Do you know any similar IC that can fit in this schematic? or i need to find a new schematic?
The link for the circuit is this: http://www.zen22142.zen.co.uk/Circui...r/l200var.html

and the schematic is this:
