Product details

Obsolete — sourcing path for the TL432IDBVRE4

No stock-holding claim; each lot is appraised on date-code spread and original packaging condition.

Adjustable shunt reference — 2.495 V to 36 V output

The reference voltage is set at 2.495 V minimum and can be programmed up to 36 V with two external resistors. Output tolerance is ±2.2%, which is tighter than the standard ±1% grade of some peers — useful for precision feedback loops in power supplies and battery chargers where the setpoint error directly affects regulation accuracy.

100 mA cathode current — load-driving capability

The device can sink up to 100 mA of cathode current, which covers most shunt-reference loads in offline flyback converters, linear regulators, and isolated DC-DC feedback paths. Below that threshold the reference drops out of regulation.

It is not qualified for automotive under-hood environments (no AEC-Q100 grade).

Frequently asked questions

Is TL432IDBVRE4 compatible with TL431?

The TL432 is functionally identical to the TL431 — same adjustable shunt-reference architecture, same 2.495 V reference voltage, same 36 V maximum output. The main difference is package: the TL432IDBVRE4 comes in SOT-23-5, while the TL431 is commonly available in larger packages like SOIC-8 or TO-92. Pinout differs between packages, so they are not drop-in replacements without a layout change.
