This chip is an old (probably obsolete) tracking regulator chip.

The only location I can find a datasheet wants me to pay for it.

I don't suppose anyone can help find a free version?

A minimalist "datasheet" is here.
The others I found in a quick scan are equally sparse.

Thanks.

Knowing it is equivalent to a se5551 got me to a more detailed datasheet.
