Product Description

Description
The LM431 is a 3-terminal adjustable shunt regulator with ensured temperature stability over the entire 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 turnon characteristics this device is an excellent replacement for many Zener diode applications.
Features
1• Average Temperature Coefficient 50 ppm/°C
• Temperature Compensated for Operation Over the Full Temperature Range
• Programmable Output Voltage
• Fast Turnon Response
• Low-Output Noise
• Low-Dynamic Output Impedance
• Available in Space-Saving SOIC-8, SOT-23, and TO-92 Packages
Applications
• Adjustable Voltage or Current Linear and Switching Power Supplies
• Voltage Monitoring
• Current Source and Sink Circuits
• Circuits Requiring Precision References
• Zener Diode Replacements
