LMV431B, LMV, Low-Voltage (1.24V) Adjustable Precision Shunt Regulators
The LMV431, LMV431A and LMV431B are precision 1.24V shunt regulators capable of adjustment to 30V.
Negative feedback from the cathode to the adjust pin controls the cathode voltage, much like a non-inverting op amp configuration (Refer to Symbol and Functional diagrams).
