Product details

2.495 V shunt reference with ±0.5% tolerance

The TL432BQDBVT is a three-terminal adjustable shunt voltage reference from Texas Instruments, offering a minimum output voltage of 2.495 V with a ±0.5% tolerance. It operates as a shunt regulator, sinking current through the cathode to maintain the reference voltage across the output and anode terminals. The ±0.5% tolerance suits precision voltage regulation in feedback loops.

Industrial temperature grade and 100 mA drive

The shunt can sink up to 100 mA continuous cathode current, enough to drive an optocoupler LED in a feedback loop or bias a small load. Minimum cathode current is 700 µA, so the part stays in regulation even at light load.

SOT-23-5 package — footprint and fit

Sourcing is limited to surplus inventory and broker channels. For new designs, consider the TL431 family in SOT-23-5 as a functional alternative — note the pinout differs, so a PCB respin may be required.

Frequently asked questions

Where can I buy TL432BQDBVT and get a price?

The TL432BQDBVT is obsolete and sourced through independent distribution.

TL432BQDBVT vs TL431 — what is the difference?

The TL432BQDBVT offers a tighter ±0.5% tolerance compared to the standard TL431's 1%. Both are 2.495 V adjustable shunt references with 100 mA output. The TL432 uses a different pinout in the SOT-23-5 package — the reference and cathode pins are swapped relative to the TL431.
