Default Low-parts high voltage MOSFET regulator


I wanted to create a simple, low parts count series pass MOSFET regulator and I simulated this using LT Spice.

According to the simulation, it should work.

However, I would like to ask for your opinon if this can be simplified further (or improved with no major additional parts) with the goal of both load and line regulation.

For low drop: output voltage not so big voltage difference with input stage you have no problem. But for big difference you will have big power dissipate at your fets like normal resistor = high temp = loss power. You can calculate the heat as loss power, imagine as a soldering iron as comparation.
