    SLVS543O – AUGUST 2004 – REVISED JANUARY 2015 TL43xx Precision Programmable Reference
    1 Features 3 Description The TL431 and TL432 devices are three-terminal
    adjustable shunt regulators, with specified thermal
    stability over applicable automotive, commercial, and
    military temperature ranges. The output voltage can
    be set to any value between Vref (approximately
    2.5 V) and 36 V, with two external resistors. These
    devices have a typical output impedance of 0.2 О©.
    Active output circuitry provides a very sharp turn-on
    characteristic, making these devices excellent
    replacements for Zener diodes in many applications,
    such as onboard regulation, adjustable power
    supplies, and switching power supplies. The TL432
    device has exactly the same functionality and
    electrical specifications as the TL431 device, but has
    different pinouts for the DBV, DBZ, and PK packages. 1 Reference Voltage Tolerance at 25В°C ...
