The LM431AIM3 from Texas Instruments is a 3-terminal adjustable shunt regulator designed for precision voltage regulation. It features guaranteed temperature stability across its operating range and a programmable output voltage that can be set anywhere from 2.5V up to 36V using two external resistors.
Key electrical characteristics include an average temperature coefficient of 50 ppm/°C and a reference voltage of 2.5V. The device is designed for operation over a wide temperature range, specified as -40°C to +85°C for industrial applications and 0°C to +70°C for commercial use.
This shunt regulator is available in a space-saving SOT-23 surface-mount package, making it suitable for designs where board space is limited. Its sharp turn-on characteristics make it an excellent alternative to traditional Zener diodes in various applications requiring stable voltage references.
