DESCRIPTION
The SPX431 is a three-terminal adjustable shunt voltage regulator providing a highly accurate
bandgap reference. The SPX431 acts as an open-loop error amplifier with a 2.5V temperature
compensation reference. The SPX431 has thermal stability, wide operating current of 150mA
and broad temperature range of 0°C to 150°C, making it suitable for a variety of applications
which require a low-cost, high performance solution. SPX431A tolerance of 0.5% is proven
to be sufficient to overcome all 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 VREF and 36 volts with
two external resistors. The SPX431 is available in SOIC-8, SOT-23-3, SOT-23-5, SOT89,
and TO-92 packages.
