Regulated Supply Section :-
Low voltage Transformer of 12 0 12 or 15 0 15 VAC connected to J1, the AC is rectified by Diode D1 D2 D3 D4 and filtered by capacitor C1 C2 C3 C4.
Voltage Regulator ic U1 is L7805 which gives an output of +5v DC.
Voltage Regulator ic U2 is L7812 / L7815 having output of +12v / +15v DC respectively.
Similarly U3 is Negative voltage regulator, L7912 / L7915 having output of -12v / -15v DC.
Unregulated Supply Section :-
High Voltage AC input received at J4 is converted in to DC by Bridge Rectifier D5.
C8 C9 C10 C11 are reservoir capacitors to filter the DC and reduce ripple.
LED D9 with R1 used to indicate supply status.
PCB designed with thick copper tracks & large solder pads to facilitate straightforward placement and soldering of components.
