🔧The PDP 1103 power supply uses a regulator circuit to control voltage output.
💡The regulator circuit consists of a three terminal regulator, overcurrent protection circuit, and crowbar circuit.
🛠️Overvoltage issues may be caused by shorted diodes or other faulty components.
🔌Checking and replacing the 7915 negative voltage regulator may solve voltage regulation problems.
🧰Troubleshoot the regulator circuit by checking diodes, capacitors, and traces for any damage or shorts.
