7805 Transistor Circuit Diagram. As mentioned earlier 7805 is a three terminal device with the three pins being 1. The following image shows the pins on a typical 7805 ic in to 220 package.
In our case the 7805 ic is an iconic regulator ic that finds its application in most of the projects. To reduce any noise spike voltage and more. Just only power transistor zener diode 5 6v and one resistor.
This 7805 ic circuit diagram designed to give fixed 5v dc at output you can choose different voltage rating ic 78xx and corresponding input power source to get desired output voltage range.
Here the operating amplifier performs as an error amplifier. We just need two capacitors of vale 33uf and 0 1uf to get this ic working. To reduce any noise spike voltage and more. As mentioned earlier 7805 is a three terminal device with the three pins being 1.
