    I have been searching the internet to no avail. I am sure there used to be a high-voltage regulator IC that came in a TO-220 package, and would take 400V or maybe more on its input, but which is now obsolete. Kinda like an LR8 but bigger.
    I think it was made by Texas, but I may have imagined that. Does anyone know the part I'm thinking of??

    Vin?
    Vout?
    Iout?

    I don't remember, but I think Vin could be as high as 400V or maybe 450V. Iout may have been 100mA or more.

    Google around Supertex.

    Do you need one?
    There are plenty of people here that can design a circuit to do that job.

    HIP5600

    Great part, now gone. Made by Harris, then they sold their semiconductor operation to Intersil. They also made an 8-pin DIP that took 110/220VAC in and made 5V out, non-isolated.

    ErnieM and absf like this.

    I don't need one per se, I just wanted to get hold of one to try out, really.

    Not much to try out. Basically it's an LM317 with a lower voltage reference and a much lower max output current (40 mA). Had to be careful about lead spacing if going for UL cert.

    The HV-2405 was a very different part, smaller package but higher output current. It reduced power dissipation by turning off the AC input after the input sinewave was above the headroom requirement.

    Wow. The good ole days when the entire schematic of a device fits on half a page in the data sheet.

    Thanks! It looks similar to the VB408. Anyone know if that is obsolete too?

    I could have sworn there was a Texas or Linear one though...
