TL431 Adjustable Precision Shunt Regulator 2.495V to 36V SOT-23-3
Precision adjustable shunt regulator 2.5V-36V, 1% accuracy, low noise, SOT-23 surface mount.
The TL431 is a precision adjustable shunt regulator from Texas Instruments, offering excellent thermal stability and a dependable reference voltage. With a typical output impedance of just 0.2Ω and a sharp turn-ON characteristic, this component provides clean, stable regulation, making it an ideal replacement for zener diodes in a wide range of circuits.
The output voltage can be programmed from approximately 2.5V up to 36V using just two external resistors, giving you flexibility in both new designs and existing applications. It supports a sink-current capability of 1 to 100mA, and its active output stage ensures consistent performance across the full operating temperature range of -40°C to 125°C.
