Hi Voltage Power supply regulator - Electronic Circuits Projects Diagrams Free

hi, I want to build a 300V, 3A DC regulated power supply for a project.
I've already got the transformer and bridge with caps built. Does anyone have a idea of a circuit for a simple regulator ?

Cheers

Check the LM723 datasheet. You can find a floating regulator application for this purpose.

Hello Sebi, thanks for your reply. i just downloaded the spec sheet as you said and found the positive floating circuit. It looks like the V2 o/p of the chip goes to the base of a high voltage transistor, i cant figure out the output arrangement of this circuit, how do i change the values to give me a steady 300V o/p ?? Thanks
