DESCRIPTION
The SPX2431 is a 3-terminal adjustable shunt voltage regulator providing a highly accurate
bandgap reference. The SPX2431 acts as an open-loop error amplifier with a 2.5V temperature
compensation reference. The SPX2431’s 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.
