## Description

The TL431C is a three-terminal adjustable shunt regulator from STMicroelectronics, designed for applications requiring precise voltage regulation. It features a wide adjustable output voltage range from Vref (approximately 2.5V) up to 36V, set using two external resistors. The device operates reliably over a temperature range of -40°C to 125°C.

With a typical output impedance of 0.2Ω and a sink current capability spanning from 1mA to 100mA, the TL431C provides active output circuitry for sharp turn-on characteristics. This makes it a suitable replacement for Zener diodes in various power supply designs, including on-board regulation, adjustable power supplies, and switching power supplies. The standard grade offers a reference voltage tolerance of 2% at 25°C.

Packaged in a TO-92 (LP) configuration, the TL431C is designed for through-hole mounting. Its specified thermal stability over commercial and industrial temperature ranges ensures consistent performance in demanding environments. The device is characterized for operation from 0°C to 70°C for the C temperature grade.
