A regulated power supply essentially consists of an ordinary power supply and a voltage regulating device as illustrated in the figure. Here are two simple ac dc power supply circuits one without a filter and one with. This circuit is very simple. Many ideas of 12v and 5v dual power supply circuit diagram at 3a max.

For a small led lamp normally we use a dc supply battery. Digital dc regulator if you are looking for 5v dc power supply for the digital. In a linear power supply the power transistor is operated in a linear mode. However having discussed the advantages of the above design it will be worth focusing on a few serious drawback this concept may include.
