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 TO-92, SOIC-8, SOT-89, and SOT-23-5 packages.
