LMV431A: Anode to cathode voltage(VCA) in comparator mode operation

Basil baby

Part Number: LMV431A
Other Parts Discussed in Thread: LMV431, LM431

Can someone help me to get the anode to cathode voltage of LMV431A in comparator mode of operation?

Thank you.

HI Basil,

Did you already ask this question previously?

Was there an additional question that wasn't answered in the previous thread?

Hi Marcoo,

I am sorry to make you confused. I mistakenly asked you the support for LM431 instead of LMV431.

Could you please share, if you have a similar application note for LMV431?

Thank you so much for all your support.

Basil

HI Basil,

We do not. The main difference between the LM431 and LMV431 is the VKA when VREF > 1.24V/2.495V.

For the LM431, When VREF > 2.495V the VKA = ~2V as the app note shows.

For the LMV431, When VREF > 1.24V the VKA = ~1V. This is the main difference between the devices. When VREF < 1.24V then VKA = ~VDD
