TL432CSF
HTC Korea TAEJIN Tech · Voltage Reference · SOT-23
TL432CSF from HTC Korea TAEJIN Tech, in a SOT-23. 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 of the 1.24 V band-gap; the datasheet gives a reference input current of 0.25 µA typical and 0.5 µA maximum at R1 = 10 kΩ, R2 = ∞, and the deviation of IREF over temperature is 0.05 µA typical and 0.3 µA maximum. |
| 2 | Anode | power_in | Anode is listed as Ground in the pin description table, and the cathode-to-anode voltage absolute maximum is VKA = -20 V to 20 V range per the absolute maximum table (cathode voltage −20 V minimum). |
| 3 | Cathode | passive | Cathode is the shunt current terminal with a recommended cathode voltage of VREF to 18 V and a recommended cathode current of 0.1 mA to 100 mA, and the absolute maximum cathode current is 100 mA. |
