PRODUCT DESCRIPTION

The SPX3431 is a 3-terminal Adjustable Shunt Voltage Regulator providing a highly accurate 0.5 bandgap reference. SPX3431 acts as an open-loop error amplifier with a 2.5V temperature compensation reference. The SPX3431 thermal stability, wide operating current (100mA) and temperature range (0°C to 105°C) makes it suitable for all variety of applications that are looking for a low cost solution with high performance. SPX3431 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 manufactures assembly line and contribute a big Cost Savings.
