Lm317 Variable Power Supply 0 12v

If you have a 12v battery.

Lm317 variable power supply 0 12v.

Guys this is very useful power supply because some applications we require 5v and some are 9v and some applications are 12v so it is adjustable power supply for all common applications. Without any further delay let s get started. 0 28v 6 8a power supply circuit diagram using lm317 and 2n3055 this design can produce a current of 20 amps with little modification use proper rating transformer and a huge heat sink with fan. In the circuit with the components value makes the output voltage range of approximately 1 25 to 13 5 volts.

This is a 0 12v variable power supply circuit at 3 amp. A power supply whether it is a battery or a switched mode ac adapter is one of the most important tools in electronics. 1 25v to 10vdc 0 12v from 12v battery source so simple circuit. 0 12 v lm317 power supply.

In this video i m making a simple but very useful power supply to power up your electronic equipment under the current rate of 500ma and 3 15v dc voltage ran. In a normal circuit the general lm350 regulator has a start voltage of 1 25v. How to make 3 3v 5v 12v and 24v regulated power supplies using the lm317 regulator. But you have a load to use the voltage 1 5v to 10v at 0 75a.

If you are planning to build a 0 to 12 volt dc power supply unit for your work bench this article may specifically help you. Lm317 power supply circuit diagram and calculations. The lm317 will supply more than 1 amp of current to push the bases of the external power transistors and with an approximate gain of ten the combo ought to provide 15 amps or even more. You should reduce the noise as well.

The variations are done smoothly through a discrete potentiometers to obtain wide voltage ranges. A lm317 is a versatile device which helps an electronic hobbyist to build a variable voltage power supply quickly cheaply and very efficiently. Obviously you need something to supply electricity to your electronic projects. This is also lm317 based variable power supply and low noise adjustable voltage output.

Huge heat sink is required in this circuit as 2n3055 transistors produce large amount of heat at full load. Making your own power supply is also one of th.
