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.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Voltage values are with respect to the anode terminal, unless otherwise noted.
(3) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
(4) The package thermal impedance is calculated in accordance with JESD 51-7.

Figure 21. Flyback With Isolation Using TLVH431 as Voltage Reference and Error Amplifier
Figure 21 shows the TLVH431 used in a 3.3-V isolated flyback supply. Output voltage VO can be as low as
reference voltage VREF (1.24 V). The output of the regulator plus the forward voltage drop of the optocoupler LED
(1.24 + 1.4 = 2.64 V) determine the minimum voltage that can be regulated in an isolated supply configuration.
Regulated voltage as low as 2.7 Vdc is possible in the topology shown in Figure 21.

(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
