TL432AQDBVR

Texas Instruments · Voltage Reference · SOT-23-5

TL432AQDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection on the TL432 DBV (SOT-23-5) package; pin may be left floating.
2 ANODE power_in Common reference pin for the device; all other pin voltages are specified relative to this pin, and it is normally connected to circuit ground.
3 NC unconnected No internal connection on the TL432 DBV (SOT-23-5) package; pin may be left floating.
4 CATHODE bidirectional Shunt (parallel) current/voltage node; can be regulated from VKA = Vref (≈2.5V) up to 36V with a recommended continuous cathode current of 1mA to 100mA (absolute maximum continuous cathode current range −100mA to 150mA).
5 REF input Reference/threshold input measured relative to ANODE; internally forced to ≈2.5V when properly biased, requires a reference input current of typically 2µA (max 4µA, absolute maximum −0.05mA to 10mA) to bias the internal transistor correctly.
