The LMV431A series precision Shunt Regulator 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. A two-resistor voltage divider terminated at the adjust pin controls the gain of a 1.24V band-gap reference. Shorting the cathode to the adjust pin (voltage follower) provides a cathode voltage of a 1.24V. The LMV431A has respective initial tolerance of 1% and functionally lend themselves to several applications that require zener diode type performance at low voltages. Applications include a 3 to 2.7V low drop-out regulator, an error amplifier in a 3V offline switching regulator and even as a voltage detector. These parts are typically stable with capacitive loads greater than 10nF and less than 50pF.
