Simple Regulated Power Supply Circuit Diagram

In case you wanted to achieve a fixed 12v regulated power supply the same configuration could be applied for getting the required results as shown below.

Simple regulated power supply circuit diagram.

Simply said it is a power supply that can adjust the output voltage or current. This component will give a stable output voltage of 5v up to 1 5 a. First power supply circuit is built with bd139 one zener diode and a few passive components. It will keep a stable voltage when it.

I want to base the power supply circuit around the lm7805 voltage regulator because it s an easy to find chip that is simple to use. 12v bd139 power supply circuit. Regulated power supply block diagram. In the above diagram we can see how an ordinary 7805 regulator ic could be used for creating a fixed 5v regulated output.

12v dc power supply schematics. Making a fixed 12v regulator circuit. 18v dc power supply using 7818. What is a variable power supply.

5 volts low dc regulator circuits. We use the simple zener diode voltage regulator as main ideas and two transistors to increase current to the load at 1a 2a. But it still has the same characteristics as a fixed regulated power supply. Designing the power supply.

Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings.
