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.
