Description
Compact Technology TL431CN Surface Mount Adjustable Precision Shunt Regulator, Programmable Precision Reference 2.495V to 36V 100mA 3-Pin SOT-23
The TL431 series are three-terminal adjustable regulators with guaranteed thermal stability over applicable temperature ranges. The output voltage may be set to any value between VREF (approximately 2.5 volts) and 36 volts with two external resistors. These devices have a typical dynamic output impedance of 0.2 Ohm. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacement for zener diodes in many applications.
