I saw "down there" that you have OrCad (PSpice) program. I think there`s a model for DN2540 on the "Supertex" pages. Some simulations would be nice... For example, we can find output resistance of the circuit - use small input AC voltage (say 50mV) and measure output voltage on the large load (several Megs), say we`d get 0,8V. Then lower the load resistor til you got half of it - 0,4V, it means that output resistance is equal to the load resistance.
BTW - I don`t have this program and real DN2540...
