Description of TLV431B

The TLV431 device is a low voltage 3-terminal adjustable voltage reference with specified thermal stability over the applicable industrial and commercial temperature ranges. The output voltage can be set to any value between VREF (1.24V) and 6V via two external resistors (see the Parametric Measurement Information section). These devices feature a lower operating voltage (1.24V) than the widely used TL431 and TL1431 shunt regulator references.

When used with optocouplers, the TLV431 device is an ideal voltage reference in isolated feedback circuits for 3V to 3.3V switch-mode power supplies. The typical value of its output impedance is 0.25Ω. Active output circuits provide very sharp turn-on characteristics, making them an excellent replacement for low-voltage Zener diodes in many applications including on-board regulation and adjustable power supplies.
