Regulated Power Supply Circuit Diagram

Simply said it is a power supply that can adjust the output voltage or current.

Regulated power supply circuit diagram.

A regulated power supply converts unregulated ac alternating current to a constant dc direct current a regulated power supply is used to ensure that the output remains constant even if the input changes. Circuit diagram 5v power supply circuit using 7805 voltage regulator. The block diagram of a regulated power supply mainly includes a step down transformer a rectifier a dc filter and a regulator. What is a variable power supply.

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. It will keep a stable voltage when it has any load. Datasheet of 7805 prescribes to use a 0 01μf capacitor at the output side to avoid transient changes in the voltages due to changes in load and a 0 33μf at the input side of regulator to avoid ripples if the filtering is far away from regulator. In the above diagram we can see how an ordinary 7805 regulator ic could be used for creating a fixed 5v regulated output.

The output from an ordinary power supply is fed to the voltage regulating device that provides the final output. Making a fixed 12v regulator circuit. Adjustable power supply circuit. Regulated power supply block diagram a regulated power supply essentially consists of an ordinary power supply and a voltage regulating device as illustrated in the figure.
