The is Fix dc voltage regulator about 3.3V at 1A,so easy very circuit.
I used normal electronics part,so used PNP transistor 2N456 or TIP42 or TIP2955,etc.
If do you want other dc voltage,you must change ZD1 : 5.6V for 5V out put.
I made use of a 6.3Vac transformer,The output of the transformer is rectified and smoothed using 1500uF or 2200uF capacitors.
The float-voltage measured here for the 6.3V transformer was 8.4V.
The unregulated DC is regulated by the ZD1 to give the regulated supply rails for the circuit.
