Going through the rohde and schwarz smdu power supply. The -15v rail has died.

Has anyone got one of the above I.C’s knocking about they want to part with, thanks

Or do I use an lm337t ? I have one of those

I have a Motorola MC1463G here. 200mA adjustable negative regulator in metal can.
New old stock, date code 7430. I've no way of testing it but you are welcome to have it for the postage cost.

Superb I'll PM you. Many thanks, saved me some redesign that.

I dug through my collection of old Motorola power-regulators but was only, alas, able to turn up a MC1469R which is the positive-voltage version.

Many thanks to Dave. The regulator is now regulating

That IC had been hanging around in one of my component drawers for years, with little to no likelihood of my ever finding a use for it.

Thanks to this forum (i.e. Paul and his volunteers) for finally enabling it to put it to good use!
