DESCRIPTION  
The SPX431L is a 3-terminal adjustable shunt voltage regulator providing a highly accurate  
bandgap reference.The SPX431L acts as an open-loop error amplifier with a 2.5V temperature  
compensation reference.The SPX431Ls thermal stability, wide operating current (100mA) and  
temperature range (0°C to 105°C) makes it suitable for a variety of applications that require a  
low cost, high performance solution. SPX431L 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 manufacturer's assembly line and contribute a significant cost savings.  
The output voltage may be adjusted to any value between VREF and 20V with two external  
resistors. The SPX431L is available in TO-92, SOIC-8, SOT-89, and SOT-23-3 packages.
