The TL431 and TL431A are 3-terminal adjustable  
shunt regulators with specified thermal stability  
over applicable automotive, commercial, and  
military temperature ranges. The output voltage

(approximately 2.5 V) and 36 V with two external  
resistors (see Figure 17). These devices have a  
typical output impedance of 0.2 Ω. Active output  
circuitry provides  
a
very sharp turn-on  
characteristic, making these devices excellent  
replacements for Zener diodes in many  
applications, such as on-board regulation,  
adjustable power supplies, and switching power  
supplies.

The TL431C and TL431AC are characterized for  
operation from 0°C to 70°C, and the TL431I and  
TL431AI are characterized for operation from  
–40°C to 85°C. The TL431M is characterized for  
operation over the full military temperature range  
of –55°C to 125°C.
