Regulator 5V,6V,9V,10V,12V 1A By IC 7805,7806,7809,7810,7812
When you build , electronic project , that have to use , power supply regulated source.
I thinks you might something the circuit that has the height and economize with.
I begs for to advise this circuit , because use voltage regulator Ic 78XX series series.
By you can change Voltage get follow want,
- 5V = IC 7805 (5v voltage regulator),
- 6V = IC-7806
- 8V = IC-7808 ,
- 9V = IC-7809 ,
- 10V = IC-7810 ,
- 12V = IC-7812
such as. By still use PCB and other equipment as before.
To use transformer 1-2A. IC-78xx to Hold Heatsink.
For example circuit that use IC-78xx series in fixed voltage supply for digital circuits
Power Supply 5V 1A by IC 7805
I am built this dc regular circuit, is the first project. Because at that interesting about digital circuits, need a constant 5V 1A fixed power supply. Using IC-7805 is very suitable for this job. Because it is easy to use, easy to buy, as popular applications, and it is also cheap.
For working principle, I would permitted to tell simply. When the home electric source ACV, 110V or 230V or a 220V, depending on your country, through the transformer, the voltage remains 9VAC. Then through the diode for rectifier power supply to the DCVolt, And a filter circuit with Capacitors. This is a voltage is about 12Vdc. It does not work through IC-7805, before our hero, for to control a stable 5V voltage with can prevent also a short circuit. Just now I have a small circuit great ready to use it.
7806 dc regulator 6V
The main parts of this circuit is IC 7806,It is normal IC linear dc voltage regulator 6V at 1A current.
It is easy project electronic because used the minority part and low cost too.
I have of a 9Vac 1A transformer,The output of the transformer is rectified by diode 1N4001 or equivalent to more high power,
Thence to smoothed filter using 470uF 35V capacitors,so the volt this is unregulated DC voltage have value 11V-12V DC.
Besides must use this ic with a suitable heatsink.
