Yep . . . . .that circuit was what I built up on a custom built board with an I.C. plug in socket for testing those devices
to evaluate one to see if it was basically good.
Seems like that family was introduced in the mid-late nineties.
A 100 ohm load resistor was used to present a challenging load for its capacitive doubler circuit .
Nowadays that chip still seems to be the principal building block for computer power supplys and others.
