TL431 Adjustable Precision Shunt Regulator 
TL431AlphaQty: 6000

 
50 for $4.50 
100 for $7.99 
500 for $25.00 
 

DESCRIPTION: The TL431 and TL431A are three-terminal adjustable shunt regulators with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical output impedance of 0.2 Ohm. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies.

FEATURES:
  • Equivalent Full-Range Temperature Coefficient ... 30 ppm/°C
  • 0.2 Ohm Typical Output Impedance
  • Sink-Current Capability ... 1mA to 100mA
  • Low Output Noise
  • Adjustable Output Voltage ... Vref to 36V

These are new and unused.
