The Interesting timer IC for a long time. And easy to use.
This is LM383 Amplifier circuit 7W,suited for automotive or many car systems-14.4V,high current capability 3.5A. It is current limited,thermally protected
The CD4013 or IC-4013 is a CMOS logic chip with two D-Type (DATA) Flip-flops. A clock pulse flow to C (clock pin), will store the data at the D input. Connect clock and a both Q output to make a toggle flip-flop for counting.
The simplest constant current source that use a small IC only. See more!
It is best a fixed regulator IC that high quality than 78xx series IC. It full 1A current output and not heat. Learn it more!
