SGM431XN3LG/TR

SGM431XN3LG/TR is a precision programmable shunt voltage reference that can be used in many applications. It is a three-terminal adjustable-output device that can keep stable under all capacitive loads. It requires two external capacitors in application to set the output voltage is to any value between VREF and 36V. The SGM431x features low dynamic impedance, low noise, and low temperature coefficient to ensure a stable output voltage over a wide range of operating temperatures and currents. This high performance makes it very suitable for multiple applications, such as precision audio components and flyback switching power supplies. Application includes portable, battery-powered equipment voltage monitoring, flyback switching power supplies, instrumentation, product testing, precision audio components.
