description/ordering information
The TLV431 is a low-voltage 3-terminal adjustable voltage reference with specified thermal stability over
applicable industrial and commercial temperature ranges. Output voltage can be set to any value between V
REF
(1.24 V) and 6 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 TLV431 is an ideal voltage reference in isolated feedback circuits for 3-V
to 3.3-V switching-mode power supplies. These devices have a typical output impedance of 0.25 Ω. Active
output circuitry provides a very sharp turn-on characteristic, making them excellent replacements for
low-voltage Zener diodes in many applications, including on-board regulation and adjustable power supplies.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

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.
NOTES: 1. Voltage values are with respect to the anode terminal, unless otherwise noted.
2. Maximum power dissipation is a function of T (max), θ , and T . The maximum allowable power dissipation at any allowable

Figure 18. Flyback With Isolation Using TLV431, TLV431A, or TLV431B
as Voltage Reference and Error Amplifier
Figure 18 shows the TLV431, TLV431A, or TLV431B used in a 3.3-V isolated flyback supply. Output voltage V
O
can be as low as reference voltage V
(1.24 V 1%). The output of the regulator, plus the forward voltage
REF
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 18.

Eco Plan
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS
&
no Sb/Br)
-
please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.

Eco Plan
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS
&
no Sb/Br)
-
please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
