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 pensation 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 overe all other errors in the system to virtually eliminate the need for trimming in the power supply manufacturer's...
