About this product
The TL431 is a programmable precision shunt regulator and voltage reference in a SOT-23 package. The output voltage is set by a two-resistor divider between the output and the REF pin. It is commonly used as the feedback element in AC-to-DC switching power supplies and as a precision current limiter.

Frequently asked questions
What is the price of TL431 Adjustable Precision Shunt Regulator SOT-23 in Egypt?
TL431 Adjustable Precision Shunt Regulator SOT-23 currently costs between 3 and 3.5 EGP across 2 offers in Egypt.
Where can I buy TL431 Adjustable Precision Shunt Regulator SOT-23 in Egypt?
TL431 Adjustable Precision Shunt Regulator SOT-23 is available from Makers Electronics and UGE. Compare the offers above to find the best price.
How do I set the output voltage of the TL431?
Connect a resistor divider from the output (cathode) to the anode, with the REF pin at the midpoint. The output is approximately 2.5 V × (1 + R1/R2), where R1 is between the output and REF and R2 is between REF and the anode.
Does the TL431 need a minimum bias current?
Yes. It needs a minimum cathode current to regulate, so the series resistor from the supply must be sized to provide it. Check the datasheet for the exact minimum value.
