Simple Regulated Power Supply Circuit Diagram

12v bd139 power supply circuit.

Simple regulated power supply circuit diagram.

What is a variable power supply. In the above diagram we can see how an ordinary 7805 regulator ic could be used for creating a fixed 5v regulated output. First power supply circuit is built with bd139 one zener diode and a few passive components. 18v dc power supply using 7818.

But it still has the same characteristics as a fixed regulated power supply. Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings. 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. This component will give a stable output voltage of 5v up to 1 5 a.

Simply said it is a power supply that can adjust the output voltage or current. Adjustable power supply circuit. Regulated power supply is an electronic circuit that is designed to provide a constant dc voltage of predetermined value across load terminals irrespective of ac mains fluctuations or load variations. 5 volts low dc regulator circuits.

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. This regulated power supply included a transformer t1 a bridge d1 d4 and the 38v dc filtering voltage regulator circuits which consists of c1 c2 r1 r2 r3 q1 and q2. It will keep a stable voltage when it. We use the simple zener diode voltage regulator as main ideas and two transistors to increase current to the load at 1a 2a.

Making a fixed 12v regulator circuit.
