This regulator use adjustable regulator ic of lmhv and a power pnp transistor of 2n Further, both line and load regulation are bet- ter than standard fixed regulators.
LM317HV Datasheet PDF
Datasheet says, ” Since the regulator is floating and sees only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input to output differential is not exceeded, or in other words, do not short the output to ground.
