TINA-TI_ENGLISH: wired simulation results for LM4040

Hi,

We cannot provide support for a non-TI model like the one being used, I recommend reaching out to the developer of this model for support.

OK
I understand that,
so I do exactly the same with the TI model (suggested in the other thread) -> https://www.ti.com/lit/zip/snom433

but again the same questions:

when simulating a 5V shunt reference LM4050 (DC Transfer Characteristic)
I get different results when connecting the circuit to GND or connecting the circuit to Vneg

in each case the voltage across the circuit VM2 is from 0V to 30V
so the simulation results should be the same for VM1, right ?

--> see screenshots

I do not understand why this happens ... ?

LM4050_NA5P0.TSC

Hi,

I've looked into this issue and the model does have an issue with negative voltages on the anode. We will work on a fix for the model and I will provide an update when the new version is available.

-Henry 

thanks a lot,
I will wait for it ...

I'm not sure if I understand this correctly:
The voltage "VM2" across the circuit is between 0 V and +30 V in both cases,
so IMHO there is never a negative voltage at the anode (relative to the cathode) [?].
