Hi all I need to design a cheap circuit (with bjt linear regulator) capable of regulating the voltage dropout on a power supply line independently from the supply current but dependently from the supply voltage.
The circuit should be able to generate a (for example) 5V dropout on the line if the input voltage is grater than 40V and should have a low dropout (ideally zero) when the input is smaller than 40V.
Could someone help me in making it in the cheapest way?
