DESCRIPTION
The SPX43 is a three-terminal adjustable shunt voltage regulator providing a highly accurate bandgap reference. The SPX431 acts as an open-loop error amplifer 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 suffcient to overcome all other errors in the system to virtually eliminate the need for trimming in the power supply manufacturers assembly line and contribute a signifcant 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.
