The Texas Instruments TL431C is a three-terminal adjustable shunt regulator designed for precision voltage regulation. It allows users to set the output voltage anywhere between its reference voltage (approximately 2.5V) and 36V using two external resistors. This device is characterized by its specified thermal stability over automotive, commercial, and military temperature ranges.
The TL431C features a typical output impedance of 0.2Ω and a sink-current capability ranging from 1mA to 100mA. It is available in different grades with initial voltage tolerances at 25°C of 0.5% (B grade), 1% (A grade), and 2% (Standard grade). The operating temperature range is from -40°C to 125°C, ensuring stable performance in demanding environments. Typical temperature drift is noted as 6mV for the C temperature grade and 14mV for the I and Q temperature grades.
Packaged in a TO-92 (LP) package, the TL431C is suitable for through-hole mounting. Its active output circuitry provides a sharp turn-on characteristic, making it an effective replacement for Zener diodes in applications such as on-board regulation, adjustable power supplies, and switching power supplies. The TL43xxC devices are specifically characterized for operation from 0°C to 70°C.
