Battery Power Equipment  
The SP431 is high-voltage three-terminal  
adjustable voltage references, with specified  
thermal stability over applicable industrial and  
commercial temperature ranges. Output voltage  
can be set to any value between VREF (2.5V) and  
36V with two external resistors. These devices  
have a typical output impedance of 0.25Ω. Active  
output circuitry provides a very sharp turn-on  
characteristic, making the SP431 excellent  
replacements for low-voltage Zener diodes in  
many applications, including onboard regulation  
and adjustable power supplies.
