LM431ACZ Description

Short technical summary and product information.

The Texas Instruments LM431ACZ is a 3-terminal adjustable shunt regulator designed for temperature-stable operation over its entire operating range. The 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 (Iz) of 400 µA, and a maximum output current (Iout) of 100 mA. The device features a temperature coefficient of up to 97 ppm/°C, with an average of 50 ppm/°C, ensuring stable 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 packages including TO-92, SOIC-8, and SOT-23, making it suitable for various board space-constrained applications.
