15V DC power supply circuit using LM7815 IC. LM7815 is a fixed volage regulator IC with three leads for input, output and ground. The IC requires very few external components and provides fixed 15V DC output with upto 1.5A current. The circuit is using 230V to 15V AC transformer to
convert the AC mains to 15V. You can also use 110V to 15V in the place of 230V transformer. The 2 ampere bridge diode is used for AC to DC conversion and 1N4001 diode is used to block the feedback to the IC. The IC become hot during the operation due to which a suitable heatsink is required.
