Adjustable shunt reference — 2.495 V minimum, 36 V maximum output
It sets a reference voltage at 2.495 V minimum and can be programmed up to 36 V using two external resistors. The ±2.2% tolerance on the reference voltage is a mid-grade bin — tighter than the standard 2% bin, looser than the 1% or 0.5% options in the TL432 family. The shunt topology means it sinks current from a supply through a series resistor — no separate bias supply needed, which simplifies the BOM in isolated or high-voltage rails.
Obsolete — plan for a replacement now
The TL432 family is broad — the TL432BIDBVR (active, ±0.5%) or TL432AIDBVR (active, ±1%) in the same SOT-23-5 footprint are the closest parametric matches, but verify the tolerance bin and output voltage range against your BOM before substituting. For new designs, avoid this part number.
Package and footprint — SOT-23-5 / SC-74A
The device is supplied in an SC-74A (SOT-753) package, also commonly referred to as SOT-23-5. The five-pin footprint is shared across the TL432 family, so a layout designed for the TL432IDBVRG4 will accept most active TL432 variants in the same package without board changes. Shipping form is Tape & Reel (TR), standard for automated pick-and-place assembly.
