The Perfect FM Radio Circuit using TDA7000 IC

Last Updated on April 26, 2025 by Swagatam Leave a Comment

Here we are going to see how we can build a very simple, yet perfect FM radio circuit using one single IC called TDA7000. This IC already has everything inside it, so we do not need to do too much headache wiring around it. First of all, before we build, we must understand what each […]

IC LM7912, -12V Negative Voltage Regulator Explained

Last Updated on April 25, 2025 by Swagatam Leave a Comment

In this post we are going to learn about one super old but gold IC called LM7912 or simply IC 7912. This one is not positive regulator like 7805 or 7812, but it is negative regulator which means it gives -12V output and not +12V. If you are making op-amp circuits or dual power supply […]
