The TL431C is a three-terminal adjustable shunt regulator manufactured by Texas Instruments. It provides a stable output voltage that can be set anywhere between its reference voltage (approximately 2.5V) and 36V using two external resistors. This device is characterized by its specified thermal stability over various temperature ranges, including commercial and military specifications.
Key electrical characteristics include a reference voltage tolerance of 2% at 25°C, with other grades offering 1% and 0.5%. The typical output impedance is 0.2Ω, and it supports a sink current capability ranging from 1mA to 100mA. The operating temperature range for the TL431C is from -40°C to 125°C, with specific characterization for the C variant from 0°C to 70°C.
With its active output circuitry, the TL431C exhibits a sharp turn-on characteristic, making it a suitable replacement for Zener diodes in applications such as on-board regulation, adjustable power supplies, and switching power supplies. The device is available in a TO-92 (LP) package and is designed for through-hole mounting.
