Ic Regulated Power Supply Circuit Diagram

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.

Ic regulated power supply circuit diagram.

Transistor variable power supply 1a 0 30v. Pins 1 2 and 3 are the input output and ground. Voltage regulator ics are inexpensive under two dollars and with just three pins to connect easy to. 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.

But it still has the same characteristics as a fixed regulated power supply. Nowadays all the power supplies use ic s to reduce ripples enhance voltage regulation and for widened control options. What is a variable power supply. 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.

It will keep a stable voltage when it has any load. In the above diagram we can see how an ordinary 7805 regulator ic could be used for creating a fixed 5v regulated output. A power supply that incorporates a voltage regulator is called a regulated power supply. 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.

Simply said it is a power supply that can adjust the output voltage or current. The following image shows the circuit diagram of producing a regulated 5v from ac mains supply. The figure above shows the application of lm340 ic as a voltage regulator.
