Ic 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.

Ic regulated power supply circuit diagram.

A power supply that incorporates a voltage regulator is called a regulated 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. Adjustable power supply circuit. Pins 1 2 and 3 are the input output and ground.

Transistor variable power supply 1a 0 30v. You can design your own voltage regulator circuit but it s far too easy to buy one of the many available integrated circuit ic voltage regulators. The internal circuitry of a regulated power supply also contains certain current limiting circuits which help the supply circuit from getting fried from inadvertent circuits. When there is quite a distance in cms from the ic to the filter capacitor of the unregulated power supply there may occur unwanted oscillations within the ic due to lead inductances within the circuit.

But it still has the same characteristics as a fixed regulated power supply. The following image shows the circuit diagram of producing a regulated 5v from ac mains supply. Simply said it is a power supply that can adjust the output voltage or current. 230v 12v step down transformer bridge rectifier or 4 pn diodes 1n4007 1a fuse 1000μf capacitor 7805 voltage regulator ic 0 22μf capacitor 0 1μf capacitor 1n4007 diode.

The figure above shows the application of lm340 ic as a voltage regulator. Nowadays all the power supplies use ic s to reduce ripples enhance voltage regulation and for widened control options. Making a fixed 12v regulator circuit.
