Product details

Adjustable shunt reference — ±1% tolerance, 100 mA cathode current

It provides a 2.495 V reference with ±1% initial tolerance and can sink up to 100 mA through the cathode, making it a common choice for precision voltage references in feedback loops, linear regulators, and monitoring circuits.

Package and rework — SOT-23-5, hot-air friendly

Housed in a 5-pin SOT-23-5 (SC-74A) package, this part is surface-mount and ships on Tape & Reel. The small footprint is straightforward to rework with a hot-air station — the pads are accessible and the body is small enough that a directed hot-air nozzle at 300°C for 10–15 seconds lifts the part cleanly without lifting adjacent pads.

Frequently asked questions

What is the tolerance of TL431AIDBVRE4?
