DESCRIPTION
The SPX2431L is a 3-terminal adjustable shunt voltage regulator providing a highly accurate bandgap reference (0.5%) and extremely low operating current (100µA). The SPX2431L acts as an open-loop error amplifier with a 2.5V temperature compensated reference. The SPX2431Ls thermal stability, wide operating current (100mA) and temperature range (0°C to 150°C) makes it suitable for a variety of applications. SPX2431LA 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 manufacturers assembly lines and contributes a significant cost savings.
