The LMV431, LMV431A and LMV431B are precision 1.24Vshunt regulators capable of adjustment to 30V. NegaTIvefeedback from the cathode to the adjust pin controls thecathode voltage, much like a non-inverTIng op amp configuraTIon(Refer to Symbol and FuncTIonal diagrams). A tworesistor voltage divider terminated at the adjust pin controlsthe gain of a 1.24V band-gap reference. Shorting the cathodeto the adjust pin (voltage follower) provides a cathodevoltage of a 1.24V.
