PRODUCT DESCRIPTION
The AS2431L is a 3-terminal Adjustable Shunt Voltage Regulator providing extremely low operating current of 100
μ
A with a highly
accurate 0.5% bandgap reference. AS2431L acts as an open-loop error amplifier with a 2.5V temperature compensation reference.
The AS2431L thermal stability, wide operating current (100mA) and temperature range (105
°
C) makes it suitable for a broad range of
applications.
AS2431L tolerance of 0.5% 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 makes this precision reference an excellent error amplifier.
