SPX431A Precision Adjustable Shunt Regulator November 8, 2022 Rev. 2.0.1 GENERAL DESCRIPTION The SPX431A is a three-terminal adjustable shunt voltage regulator providing a highly accurate bandgap reference. The SPX431A acts as an open-loop error amplifier with a 2.5V temperature compensation reference. The SPX431A has thermal stability, wide operating current of 150mA and broad temperature range of -40°C to 125°C, making it suitable for a variety of applications which require a low-cost, high performance solution. The SPX431A tolerance of 0.5% is proven to be sufficient to overcome all other errors in the system to virtually eliminate the need for trimming in the power supply manufacturer's assembly line and contribute a significant cost savings.
