12v To 5v Converter Circuit. The capacitors are there to smooth out certain spikes due to increased current requirements. Connect 5v input to 1k resistor.
Which is a simple circuit using ic 7805 to the fixed regulator 5 volts and tip41 npn power transistor to increase current up to 2a. So what s happening is that on the input side you give the 12v dc input and the ic regulates that voltage and gives an output of ideally 5v 4 8v to 5 2v as per its datasheet. Here is the 12v to 5v dc converter circuit for low current applications 70 ma mainly for taking reference emf voltage and in a small current draining circuit like an led indicator.
