PRODUCT DESCRIPTION
The AS3431 is a 3-terminal Adjustable Shunt Voltage Regulator providing a highly accurate 0.5% bandgap reference. AS3431 acts as
an open-loop error amplifier with a 2.5V temperature compensation reference. The AS3431 thermal stability, wide operating current
(100mA) and temperature range (0
°
C to 105
°
C) makes it suitable for all variety of applications that are looking for a low cost solution
with high performance.
AS3431 tolerance of 0.5% is proven to be sufficient to overcome all the other errors in the system to
virtually eliminate the need for trimming in the power supply manufactures assembly line and contribute a big 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 make this precision reference an excellent error amplifier.
The AS3431 is a direct replacement for the AS431 and TL431 in low voltage, low current applications.
AS3431 is also available in
SOT-89 and TO-92.
