i want to design a simple high voltage poersupply using 317 using the reference design given in the databook wherein Vo is 100V & Io is 1A. I want to replace the transistors by mosfet. what necessary adjustments should I make?

    Hello,

    The example you attached is for 25mA and under, which will still require some good heat sinking. However, running at 1A will mean dissipating 70W! This will not work with a Linear Regulator.

    What's the application that requires this power design?

    Thanks,
