A linear voltage regulator is the easiest to deal with. It is very easy to create and do not need much technical knowledge to understand its behavior. It has two variations: series and shunt.
Switching power supply operation is very different to that of linear power supply. Despite of its complexity, higher bill of material cost and higher parts count, switch mode power supply is still the preferred power supply topology in the market nowadays. The main reason is higher efficiency and higher power density. Higher efficiency simply means that only a small portionREAD
In linear power supply design output regulation is not a question because it is easily done by the linear regulator inserted before the load. Nowadays linear power supply is not anymore widely used. What is drawing more attention now is the switch mode power supply. How switch mode power supply regulates its output is different from what linear regulator does.READ
