Product Change Notification
The LM431SA/LM431SB/LM431SC are three terminal output adjustable regulators with thermal stability over operating temperature range. The output voltage can be set any value between VREF (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 Ω. Active output circuit provides a sharp turn-on characteristic, making these devices excellent replacement for Zener Diodes in many applications.
Features
 
  • Programmable Output Voltage to 36 V
  • Low Dynamic Output Impedance 0.2 Ω Typical
  • Sink Current Capability of 1.0 to 100 mA
  • Equivalent Full-Range Temperature Coefficient of 50 ppm/°C Typical
  • Temperature Compensated for Operation Over Full Rated Operating Temperature Range
  • Low Output Noise Voltage
  • Fast Turn-on Response
Applications
  • This product is general usage and suitable for many different applications.
