18V DC power supply by 7818

When i want dc regulator power supply 18V 1A.I like this circuit because it is easy to make.
The main parts of the are the IC 7818 and the 1000uf 35V capacitors.
I used the 18VAC 1A transformer,The output of the transformer is rectified by diode 1N4007 or equivalent.
The voltage here is unregulated value 24V to 26V DC.
You must use the IC1 with a suitable heatsink.
