tl431 pspice
What modifications are needed to convert C. Bassos TL431 Pspice model
to a TLVH431 model? The TLVH431 is the Low Voltage low current version of the TL431.
I tried the obvious switching the 2.495V to 1.24V but I get a
reference of 1.49V when I do this, it should be 1.24V.
This is the TL431 model.
Thanks
