I have a MPX4250AP and I was looking at the technical document. In there it mentions V1, V2 and Vex for this casing but makes no mention as to functionality. What are these pins?
V1, V2 and Vex pins are used for factory trimming and we recommend to leave these pins unconnected. You will require only pin #1 (Vout), pin #2 (Ground) and pin #3 (Vs) as shown in figure 1 of the data sheet.
