Re: 135 Vdc Voltage Regulator

I have several of the LM317H laying around, I am just not sure how to make sure that the input tracks the output fast enough. <p>The amount of current I need is only 20 - 50 mA. very small.

135 Vdc Voltage Regulator

I am working on a power supply for an antique radio and need to design a regulator for the 135Vdc section of the power supply. Besides using a series of Zeners to create the voltage, is there a good regulator like the LM317 that will work for voltages that high? <p>Thanks,
