TL431IDBZR Description

For TL431 and TL432, there are pin-to-pin substitutes called TL431IDBZR devices. For increased system accuracy, the TL431IDBZR provides superior stability, less temperature drift (VI(dev)), and lower reference current (Iref). The three-terminal adjustable shunt regulators with specified thermal stability over relevant automotive, commercial, and military temperature ranges are known as TL431IDBZR devices.

TL431IDBZR Features

• output voltage that can be changed: Vref to 36 V

• Operation between -40 and 125 °C

• Regular temperature fluctuation (TL43xB)

• Minimal Output Noisy

• 0.2-Ω average output impedance

• Capable of sinking currents between 1 and 100 mA

TL431IDBZR Applications

• Voltage and current referencing that is adjustable

• Flyback SMPS secondary side regulation

• Replacement for Zener

• voltage observing

• Comparison tool with built-in reference
