About this product
The TL431 is a three-terminal adjustable shunt regulator that acts as a programmable Zener diode, with an output adjustable up to 36 V. Its dynamic output impedance is typically 0.2 Ω. It is used as a voltage reference, in feedback loops of switch-mode power supplies and in overvoltage detection, and it can replace Zener diodes in many designs.

Where can I buy TL431 Adjustable Shunt Voltage Reference up to 36V TO-92 in Egypt?
TL431 Adjustable Shunt Voltage Reference up to 36V TO-92 is available from Makers Electronics. Compare the offers above to find the best price.
How do I set the output voltage of the TL431?
Use two resistors from the cathode to the reference pin (R1) and from the reference pin to the anode (R2), usually with the anode at ground. The output is Vout = 2.495 V × (1 + R1 / R2).
Do I need a series resistor?
Yes. A series resistor from the supply to the cathode limits the current, which must stay within the 1 mA to 100 mA range for regulation. Calculate it from the supply voltage and the expected load current.
