SPX431CN-L [MAXLINEAR]

The SPX431 is a three-terminal adjustable shunt voltage regulator providing a highly accurate bandgap reference. It acts as an open-loop error amplifier with a 2.5V temperature compensation reference. The device has thermal stability, wide operating current of 150mA and broad temperature range, 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 significant cost savings. The output voltage may be adjusted to any value between VREF and 36 volts with two external resistors. Available in SOIC-8, SOT-23-3, SOT-23-5, SOT-89, and TO-92 packages.
