Product details

Adjustable shunt reference – 1.24 V bandgap, 6 V ceiling

It sinks up to 15 mA through the cathode, and the minimum cathode current to keep it regulating is 80 µA.

If your design sees sustained junction temperatures above 85°C – say, under-hood automotive or a hot motor-drive enclosure – you need the TLV431AIDBVR (same part, wider temp grade) or an AEC-Q100 qualified variant.

SOT-23-5 – field-swappable with basic tools

The SOT-23-5 package (SC-74A, SOT-753) is a standard five-lead small-outline transistor package.

Frequently asked questions

What is the exact tolerance and temperature drift of TLV431AIDBVT?

The reference voltage tolerance is ±1% at 25°C.

Can TLV431AIDBVT replace TLV431A directly?

Yes, the TLV431AIDBVT is a specific package and temperature variant of the TLV431A family. It shares the same electrical specifications (1.24 V reference, ±1% tolerance, 15 mA output, 80 µA cathode current) and the same SOT-23-5 pinout. If your board is laid out for a TLV431A in SOT-23-5, this part drops in without changes.
