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.
