LM431AIM Description

Short technical summary and product information.

The LM431AIM from Texas Instruments is a 3-terminal adjustable shunt regulator designed for temperature stability over its operating range. The output voltage can be set anywhere between 2.5 V and 36 V by selecting two external resistors, making it a versatile replacement for Zener diodes.

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 typical average temperature coefficient of 50 ppm/°C and a maximum temperature coefficient of 97 ppm/°C, ensuring reliable performance across its -40°C to 85°C operating temperature range.

Available in space-saving packages such as TO-92 (LP), SOIC (D), and SOT-23 (DBZ), the LM431AIM is suitable for various applications requiring precise voltage regulation. Its fast turn-on response, low output noise, and low dynamic output impedance further enhance its utility in circuit design.
