Other Parts Discussed in Thread: TINA-TI,
Tool/software: TINA-TI or Spice Models
Hi team,
My customer is working with an IC ‘TLV431’ in one of our designs and was trying to simulate it on LTspice.
We created a symbol for the IC, we got the Pspice .lib file and we simulated it.
We encountered an issue prompting that, there is a missing current value for “X1”.
Could you please check for the missing current value for “X1” in the text file and lib below?
Thanks,
Eric Mitchell
