The LM431BCM3 is a 3-terminal adjustable shunt regulator designed for temperature-stable operation over its entire temperature range. The output voltage can be precisely set to any level between 2.5V and 36V by selecting two external resistors.
Key electrical specifications include a minimum regulation current of 400 µA, a maximum output current of 100 mA, and an initial accuracy of up to 0.5%. The device features a temperature coefficient of 97 ppm/°C maximum and an average temperature coefficient of 50 ppm/°C. It operates reliably within a temperature range of -40°C to 85°C.
Due to its sharp turn-on characteristics, the LM431BCM3 serves as an excellent replacement for many Zener diode applications. It is available in space-saving packages including TO-92, SOIC, and SOT-23, making it suitable for various board designs.
This shunt regulator is temperature compensated for operation over the full temperature range, offering programmable output voltage, fast turn-on response, low output noise, and low dynamic output impedance.
