Product details

Shunt reference for precision bias and regulation

It provides a 2.495 V reference minimum with an adjustable output up to 36 V, making it a common building block for precision voltage references, error amplifiers, and series-pass regulators in power supplies and instrumentation. Rated for 100 mA cathode current with a minimum cathode current of 600 µA, the device can sink enough current to drive optocoupler LEDs or bias a pass transistor in a linear regulator loop.

±1% tolerance and commercial temperature range

The ±1% tolerance on the reference voltage gives tighter output regulation than the standard ±2% TL431 grade, which matters when the reference sets the feedback threshold in a 5 V or 3.3 V supply where every millivolt of error eats into the load-regulation budget.

SOT-23-5 package and tape-and-reel delivery

The Tape & Reel (TR) packaging is feeder-ready for pick-and-place lines — no tube-to-reel conversion needed.

For BOM lines that still call out this exact code, procurement must source through independent distributors or the surplus market.

Frequently asked questions

Is the TL431ACDBVTG4 obsolete?

Yes, Texas Instruments lists the TL431ACDBVTG4 as Obsolete. No official replacement part number is provided in the lifecycle record.

Is the TL431ACDBVTG4 RoHS compliant?

The part number suffix 'G4' indicates a RoHS-compliant, green (halogen-free) finish per Texas Instruments' standard marking. No separate RoHS certificate is listed here.

What is the difference between the TL431ACDBVTG4 and the TL431AIDBVTG4?

Both share the same SOT-23-5 package and ±1% tolerance.
