Hi
We are doing a high voltage linear regulator to run off rectified 240VAC.
The following two schematics are our possible choices.
They would more cheaply be done with the FET replaced with a IGBT. What do you think of low current linear regulators using IGBTs?
(Output is 3V, 6mA max in each case)
LTspice sim also attached
