Product details

The TL432BQDBVTE4 is an adjustable shunt voltage reference with a ±0.5% tolerance on the reference voltage. The 100 mA cathode current rating and 700 µA minimum cathode current give the designer headroom for driving optocouplers or biasing error amplifiers in offline flyback supplies.

Industrial temperature grade and SOT-23-5 footprint

The 5-pin footprint is common among adjustable shunt references, but because the TL432BQDBVTE4 is obsolete, any pin-compatible replacement must be verified against the original pad layout.

Frequently asked questions

What is the accuracy (tolerance) and temperature stability of TL432BQDBVTE4?

The TL432BQDBVTE4 has a ±0.5% tolerance on the reference voltage. The datasheet provides typical temperature-drift curves; the ±0.5% tolerance is the initial accuracy at 25 °C.
