CBI · Voltage Reference · SOT-89
TL432U from CBI, in a SOT-89. 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 | REFERENCE | input | Reference input terminal, with a reference input current range of 6 μA as stated in the absolute maximum ratings. |
| 2 | ANODE | passive | Anode terminal of the shunt reference; the datasheet gives no separate electrical limit for this pin. |
| 3 | CATHODE | passive | Cathode terminal, rated for a cathode voltage of 18 V and a continuous cathode current range of 100 mA in the absolute maximum ratings. |
