PRODUCT DESCRIPTION  
The AS1431 is a 3-terminal Adjustable Shunt Voltage Regulator providing a highly accurate 0.4% bandgap reference. AS1431 acts as  
an open-loop error amplifier with a 2.5V temperature compensation reference. The AS1431 thermal stability, wide operating current  
(150mA) and temperature range (125°C) makes it suitable for all varieties of applications that are looking for a low cost solution with  
high performance. AS1431 tolerance of 0.4% is proven to be sufficient to overcome all of the other errors in the system to  
virtually eliminate the need for trimming in the power supply manufactures assembly line and contribute a significant Cost  
Savings.  
In the standard shunt configuration, the combination of low temperature coefficient (T.C.), sharp turn-on characteristics, low output  
impedance and programmable output voltage that makes this precision reference an excellent error amplifier.  
The AS1431 is a direct improved replacement for the AS431 and TL431 in low voltage, low current applications.
