IC, LM431AIM3/NOPB, Texas Instruments

The LM431AIM3/NOPB is a 3-terminal adjustable shunt regulator with ensured temperature stability over the entrie temperature range of operation. The output voltage may be set at any level greater than 2.5 V (VREF) up to 36 V merely by selecting two external resistors that act as a voltage divided network. Due to the sharp turn on characteristics this device is an excellent replacement for many Zener diode applications. Average temperature coefficient 50 ppm/°C.


  • Temperature compensated for operation over the full temperature range
  • Programmable output voltage
  • Low output noise
  • Low dynamic output impedance


  • Voltage monitoring
  • Current source and sink circuits
  • Circuits requiring precision references
