Product details

Adjustable shunt reference in a small SC-70-6 footprint

It delivers a nominal 2.495 V reference with a ±0.5% tolerance, and the output can be set to any value up to 36 V using two external resistors.

Precision grade for tighter regulation loops

The B-grade suffix denotes a ±0.5% initial tolerance on the reference voltage, tighter than the A-grade's ±1% typical. In a precision supply or ADC reference circuit, that 0.5% headroom reduces the need for trimming and keeps the output within spec across temperature and load. The shunt topology means it can sink or source current through the cathode, so it works equally well as a shunt regulator or as an error amplifier in an isolated flyback converter.

Frequently asked questions

What is the tolerance of TL431BIDCKT?

The TL431BIDCKT has a ±0.5% initial tolerance on the reference voltage, which is the B-grade specification.

Does TL431BIDCKT come in tape and reel?

Yes, TL431BIDCKT is available in Tape & Reel (TR) packaging, as well as Cut Tape (CT) options.

What is the difference between TL431BIDCKT and TL431AIDCKT?

The key difference is tolerance: TL431BIDCKT offers ±0.5% initial accuracy, while the TL431AIDCKT is typically ±1%. Both share the same SC-70-6 package, pinout, and 100 mA output capability.
