IC 7815: Full Specifications, Working, Circuit Diagram
In this post I am going to talk about this very common but very useful voltage regulator IC, that is called IC 7815. This chip is from the famous 78XX series of fixed voltage regulators. So the “15” in this number means this IC will always try to give +15V DC output, no matter what […]
Optocoupler Circuits, Working, Characteristics, Interfacing
OPTOCOUPLERS OR OPTOISOLATORS are devices that enable efficient transmission of DC signal and other data across two circuit stages, and also simultaneously maintain an excellent level of electrical isolation between them. Optocouplers become specifically useful where an electrical signal is required to be sent across two circuit stages, but with an extreme degree of electrical […]
