The LM431ACZ from On Semiconductor is a 3-terminal adjustable shunt regulator designed for temperature-stable operation. Its output voltage can be precisely set anywhere between 2.5V (VREF) and 36V by using two external resistors.
Key electrical specifications include an initial accuracy of up to 0.5%, a minimum regulation current of 400 µA, and a maximum output current of 100 mA. The device boasts a temperature coefficient of 97 ppm/°C maximum and an average temperature coefficient of 50 ppm/°C, ensuring reliable performance across its operating 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 TO-92, SOIC-8, and SOT-23 packages, making it suitable for various board space constraints. The LM431ACZ 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.
