    SNVS020H – MAY 2000 – REVISED JANUARY 2016 LM431 Adjustable Precision Zener Shunt Regulator
    1 Features 3 Description The LM431 is a 3-terminal adjustable shunt regulator
    with ensured temperature stability over the entire
    temperature range of operation. The output voltage
    may be set at any level greater than 2.5 V (VREF) up
    to 36 V merely by selecting two external resistors that
    act as a voltage divided network. Due to the sharp
    turnon characteristics this device is an excellent
    replacement for many Zener diode applications. 1 Average Temperature Coefficient 50 ppm/В°C
    Temperature Compensated for Operation Over
    the Full Temperature Range
    Programmable Output Voltage
    Fast Turnon Response
    Low-Output Noise
    Low-Dynamic Output Impedance
    Available in Space-Saving SOIC-8, SOT-23, and
    TO-92 Packages 2 Applications Adjustable Voltage or Current Linear and ...
