I've been looking for a week now and it appears there isn't such a
beast on the net. I've tried all the normal suspect places but it
appears that this doesn't exist...yet I have one on a CPU board
manufactured about 20 yrs ago....
Can anyone help out?
Hi.
I have it in my old ITT data book.

General description.
These are dual polarity tracking regulators designed
to provide balanced positive and negative output
voltages at current up to 100mA, the devices are set
for ±15v, ±12v and +5, -12v outputs respectively.
Input voltages up to ±30v can be used and there is
provision for adjustable current limiting.
Absolute Maximum Ratings.
