The TL431LIBIDBZR from Texas Instruments is a three-terminal adjustable shunt regulator designed for high-precision voltage regulation. It features optimized reference current and deviation performance, making it suitable for applications requiring high accuracy and low leakage.
The output voltage can be precisely set to any value between its reference voltage (approximately 2.495 V) and 36 V using two external resistors. This device operates over a temperature range of -40°C to 85°C and has a typical output impedance of 0.3 Ω. The TL431LIBIDBZR is housed in a compact SOT-23 package, making it ideal for space-constrained designs.
Its active output circuitry provides a sharp turn-on characteristic, serving as an excellent replacement for Zener diodes in various applications, including onboard regulation, adjustable power supplies, and switching power supplies. The device's optimized reference input current (0.4 µA max) and deviation over temperature (0.3 µA max) further enhance system accuracy.
The minimum typical output voltage is 2.495 V.
The output voltage can be adjusted from the reference voltage up to 36 V.
