Description
The TL431SN3 series are three-terminal adjustable regulators with guaranteed thermal stability over applicable
temperature range. The output voltage may be set to any value between VREF (approximately 2.495 volts) and 36
volts with two external resistors. These devices have a typical dynamic output impedance of 0.2Ω. Active output
circuitry provides a very sharp turn-on characteristic, making these devices excellent replacement for zener diodes in
many applications.
