Product details

Precision shunt reference in a three-pin SOT-23-3

It sets or divides a reference voltage between 2.495 V and 36 V with a ±0.5% tolerance, making it the go-to for tight-regulation feedback loops in AC-DC adapters, isolated DC-DC converters, and precision comparator thresholds.

Output current and cathode bias — sizing the feedback divider

The device can sink up to 100 mA through the cathode, which covers optocoupler LED drive and shunt regulation for moderate loads.

The temperature range covers the majority of non-military, non-downhole applications without the premium of an extended-temperature or AEC-qualified part.

Frequently asked questions

Can TL432BIDBZT be used as a precision reference?

Yes, with a ±0.5% tolerance and an adjustable output from 2.495 V to 36 V, it is suitable as a precision shunt reference for feedback and threshold applications.

Is TL432BIDBZT compatible with the TL431 footprint?

The TL432BIDBZT is functionally identical to the TL431 but packaged in the smaller SOT-23-3 (TO-236-3, SC-59) footprint. It is not pin-compatible with the TL431 in the larger SOT-89 or TO-92 packages — verify the PCB land pattern before substitution.
