Schematic Diagram :
The schematic shown at the top is basically the Regulated Power Supply that we created for our project in Electronics 1.
Note: Be sure to have a transformer with an ampere rating of at least 1.5 A and above. As what I have mentioned earlier, we experienced one problem that was a nuisance in our troubleshooting. That is because, when we created this project the Ampere rating that we have for our transformer was only 1 A, along with this, when you place a load a huge load, there would be a huge drop on your voltage Why??The answer to this is based on the LM317. The specification on its datasheet is that you must at least have a 1.5 A current rating in order to have this properly worked out. If not, you would experience a huge drop when you would place a load for this supply.
This is our variable regulated power supply output:
