Frequently asked questions
What is the price of TL431A Programmable Precision Shunt Regulator in Egypt?
TL431A Programmable Precision Shunt Regulator currently costs between 7 and 15 EGP across 2 offers in Egypt.
Where can I buy TL431A Programmable Precision Shunt Regulator in Egypt?
TL431A Programmable Precision Shunt Regulator is available from Microohm and UGE. Compare the offers above to find the best price.
How do I set the output voltage?
Connect the cathode to the output, place resistor R1 between cathode and reference, and resistor R2 between reference and anode. Output voltage is Vout = 2.495 × (1 + R1 / R2).
Does it need a series resistor?
Yes. A resistor from the supply to the cathode is needed to keep the cathode current within the 1 mA to 100 mA range, and the TL431A will not regulate properly below its minimum current.
