Frequently Asked Questions
How does TL431BQDCKTE4 regulate voltage in adjustable reference circuits?
TL431BQDCKTE4 is an adjustable shunt reference with a 2.495V to 36V output adjustment context and 100mA maximum output-current capability.
Which package details should contract manufacturers confirm for this TI device?
The fetched context lists a compact 6-pin SOT-23 package with JESD-30 R-PDSO-G6, so assembly teams should confirm 6 pins and reel handling.
How should buyers compare alternates for TL431BQDCKTE4?
Alternates should match the TL431B function, 2.483 V to 2.507 V reference tolerance context, 0.1 A output current rating, and SOT-23-6 footprint.
Which compliance attributes are visible for sourcing records?
The part context states RoHS-compliant lead-free construction and JESD-609 e4, while the electrical profile still centers on 36V adjustability and 100mA current.
