The XRP431L is a three-terminal adjustable shunt regulator, providing highly precise band gap reference.
The XRP431L acts as an open-loop error amplifier with a 1.24V temperature compensated reference. The XRP431L has thermal stability, wide operating current of 100mA and broad temperature range of -40°C to 125°C, making it suitable for a variety of applications which require a low-cost, high performance solution. The XRP431L 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 18 volts with two external resistors.
The XRP431L is available in a RoHS compliant, green halogen free 5-pin SOT-23 package.
