SNVS041G – MAY 2004 – REVISED SEPTEMBER 2014 LMV431x Low-Voltage (1.24-V) Adjustable Precision Shunt Regulators
1 Features 3 Description The LMV431, LMV431A and LMV431B are precision
1.24 V shunt regulators capable of adjustment to 30
V. Negative feedback from the cathode to the adjust
pin controls the cathode voltage, much like a noninverting op amp configuration (Refer to Symbol and
Functional Diagrams). A two-resistor voltage divider
terminated at the adjust pin controls the gain of a
1.24 V band-gap reference. Shorting the cathode to
the adjust pin (voltage follower) provides a cathode
voltage of a 1.24 V. 1 Low-Voltage Operation/Wide Adjust Range
