    –40°C to 125°C Specifications DESCRIPTION/ORDERING INFORMATION
    The TLVH431 devices are low-voltage 3-terminal adjustable voltage references, with thermal stability specified
    over the automotive temperature range. Output voltage can be set to any value between VREF (1.24 V) and 18 V
    with two external resistors (see Figure 2). These devices operate from a lower voltage (1.24 V) than the widely
    used TL431 and TL1431 shunt-regulator references.
    When used with an optocoupler, the TLVH431 devices are ideal voltage reference in isolated feedback circuits
    for 3-V to 3.3-V switching-mode power supplies. They have a typical output impedance of 0.25 Ω. Active output
    circuitry provides a very sharp turn-on characteristic, making the TLVH431 an excellent replacement for
    low-voltage Zener diodes in many applications, including on-board regulation and adjustable power supplies.
