the sPX43 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 V

two external resistors. The SPX431 is available in SOIC-8, SOT-23-3, SOT-23-5, SOT89,

and TO-92 packages.
