PCB Layout for Positive Voltage Regulator using 7805 and 7812

EXPERIMENT: 11. Design and create single sided PCB Layout for Positive Voltage regulator using 7805 and 7812 IC.
AIM: To design the single sided PCB layout for Positive Voltage regulator using 7805 and 7812 IC with MULTISIM.
1. PC loaded with MULTISIM software.
2. Laser printer.


• Open MULTISIM Software, Click=> File => New => Design.
• Click File => save as in Desk Top and rename the Design1 to your circuit name then save.
• Go to Component tool bar and select the components like diode capacitor, resistor, LED the click PLACE POWER COMPONENTS and SELECT voltage regulator, connect as per given circuit diagram and save it.
• Test the circuit with simulation RUN button.
• Remove transformer, Power source and output multi-meter with replacement of connector.
• Change Properties of the all component into PCB Mode.
• Set the Track width = 30 mils, trace to trace and trace to pad = 10 mils,
• Go to Transfer icon => Transfer to Ultiboard 12.0 then save the file and got Import netlist and click ok.
• Go to OPTIONS icon Select PCB Properties icon and select copper layers Click properties untick routing click ok for single side PCB.
• Select all components into Board Outline and make small pcb size with the help of board Outline.
• Click Auto route icon then click auto router to make PCB Layout.
• Finally print the PCB Layout with help of printer.
RESULT: Thus the design of a single sided PCB Layout for Positive Voltage regulator using 7805 and 7812 IC with MULTISIM software CAD tool was done.
