The LM431BCM3 is a 3-terminal adjustable shunt regulator from National Semiconductor (NS) designed for temperature-stable operation over its entire operating range. The output voltage can be programmed from 2.5 V up to 36 V 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 temperature coefficient is a maximum of 97 ppm/°C, with an average of 50 ppm/°C. The device operates within a temperature range of -40°C to 85°C.
This shunt regulator is an excellent replacement for Zener diodes due to its sharp turn-on characteristics. It is available in space-saving packages including TO-92, SOIC, and SOT-23, making it suitable for various applications where precise voltage regulation is required.
The LM431BCM3 is temperature compensated for operation over the full temperature range, features programmable output voltage, fast turn-on response, low output noise, and low dynamic output impedance.
