Working of tl431 Quiz Practice Quiz | Working of TL431

Adjustable Precision Shunt Regulator — The TL431 is designed to be used as a precision voltage reference or shunt regulator.

Reference — The reference pin is where the internal 2.5V reference voltage is available for comparison.

2.5V — The TL431 uses a 2.5V internal reference for its operation and regulation.

By varying the current flowing through its cathode and anode. — It sinks current to regulate voltage across the external components connected to it.

A resistor — Usually in parallel with a resistor to form a voltage divider and set the output voltage.
