SPX1431 Precision Adjustable Shunt Regulator April 2013 GENERAL DESCRIPTION The SPX1431 is a 3-terminal adjustable shunt voltage regulator providing a highly accurate bandgap reference. The SPX1431 acts as an open-loop error amplifier with a 2.5V temperature compensation reference. The SPX1431's thermal stability, wide operating current (150mA) and temperature range (-55°C to 125°C) makes it suitable for a variety of applications that require a low cost, high performance solution. SPX1431 tolerance of 0.4% 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 lines and contributes a significant cost savings. The output voltage may be adjusted to any value between VREF and 36 volts with two external resistors. The SPX1431 is available in SOIC-8 and SOT-89-3 packages. APPLICATIONS • Battery Operating Equipment • Adjustable Supplies • Switching Power Supplies • Erro.
