Have one to sell? In regard to this page, I have drawn up a couple of 78xx high current circuits you might like to consider. Ti3 more about the condition. I have since switched to using the better LM regulator so that I can adjust the voltage to it is far more reliable than the 78xx.


Delivery times may vary, especially during km7812 periods. Pictured above is a circuit from the Fairchild LM datasheet. People who viewed this item also viewed.

One common shortfall of these common regulators is they are rated at just 1 Amp output current. This tiny difference in voltage has the disastrous consequence of making the regulator with the lowest output voltage trying to carry all of the current.

With this set up, the power transistor and power resistor need heatsinkingand selecting the correct specification of transistor and resistor, and getting everything set up is not particularly easy. The output voltage is adjusted using a couple of resistors, and one of these resistors can be replaced with a potentiometer to give an adjustable output.
