It uses integrated number circuit LM317T be important equipment. It can have the trend comes out about 1A by is character circuit DC voltage regulated. And have the circuit protects good. We can fix output voltage get from R1,R2. The diode D3-D4 (1N4002) use protect voltage flow turn back be bad with IC get. The Capacitors in the circuit helps Filter voltage smoothly and completed most. The transformer should choose 1A -2A size for current well sir.
