LTspice LT3014HVES5 Model Accuracy

Question

Hello, 
 I am attempting to perform a worst-case circuit analysis on a design that implements the LT3014HVES5. I have two questions: 
 
 Is the LTspice model accurate for output impedance? I have the following plotted, but no measurement data to correlate to. /resized-image/__size/640x480/__key/communityserver-discussions-components-files/1020/0537.pastedimage1735605013313v1.png 
 Is there a straightforward method for tolerancing the output impedance in the model? What bounds can we use and how can we implement them? 
 
 Thank you so much! 
 Jake

Hi JakeAEI , 
 I don't believe this model has a tolerance parameter. Afraid I don't see any clear examples of implementing this outside the part. Maybe there is a clever way. 
 As far as the veracity of the curve&mdash;you would only be able to compare to bench test if no curves are published.
