This project is a basic power supply that provides fixed voltage outputs of 12V, 9V, and 5V for various applications. The design includes the following key components:
Step-down transformer (220V AC to 12V AC)
Full-wave bridge rectifier (4x diodes) for AC to DC conversion
Voltage regulators (LM7812, LM7809, LM7805) to provide stable 12V, 9V, and 5V outputs
This power supply is ideal for low-power electronic circuits that require multiple fixed voltages.
