TI LMV431AIMF/NOPB

ШунтРегулируемый-40°C ~ 85°C (TA)

Overview

The LMV431AIMF/NOPB is a 1.24V 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 operational amplifier 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. It has respective initial tolerances of 1.5, 1 and 0.5% 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 off-line switching regulator and even as a voltage detector. These parts are typically stable with capacitive loads greater than 10nF and less than 50pF.
