tl431xm3
Description
Adjustable Precision Shunt Regulators
Manufacturer
Cystech Electonics Corp.
Datasheet
TL431XM3
Description
The TL431XM3 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
2.495 volts) and 36 volts with two external resistors. These devices have a typical dynamic output
impedance of 0.2 . Active output circuitry provides a very sharp turn-on characteristic, making these
devices excellent replacement for zener diodes in many applications.
