LM431SAI: Adjustable/2.5 V, 2% Tolerance Shunt Regulator

Description: The LM431SAI is three terminal output adjustable r...
  • The LM431SAI is three terminal output adjustable regulator with thermal stability over operating temperature range from -40°C to +85°C. The output voltage can be set any value between VREF (approximately 2.5 V) and 36 V with two external resistors. This device has a typical dynamic output impedance of 0.2 Ω. Active output circuit provides a sharp turn-on characteristic, making this device excellent replacement for Zener diodes in many applications.
