SOT-23
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 V
REF
(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.
Features
Programmable output voltage
Temperature coefficient is 50ppm/°C typical
