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 SPX431L’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. 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 V_REFand 20V with two external

resistors. The SPX431L is available in TO-92, SOIC-8, SOT-89, and SOT-23-3 packages.
