Regulated Power Supply Circuit Diagram

A regulated dc power supply is also known as a linear power supply it is an embedded circuit and consists of various blocks.

Regulated power supply circuit diagram.

In the above diagram we can see how an ordinary 7805 regulator ic could be used for creating a fixed 5v regulated output. 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. 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.

The block diagram of a regulated power supply mainly includes a step down transformer a rectifier a dc filter and a regulator. But it still has the same characteristics as a fixed regulated power supply. The construction working of a regulated power supply is discussed below. Transistor variable power supply 1a 0 30v.

What is a variable power supply. Simply said it is a power supply that can adjust the output voltage or current. The output from an ordinary power supply is fed to the voltage regulating device that provides the final output. It will keep a stable voltage when it has any load.

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. 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.
