UTC Unisonic Tech · Voltage Reference · SOT-23
TL432G-AE3-R from UTC Unisonic 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 | K | passive | Cathode terminal; the datasheet rates the cathode-anode reverse breakdown voltage VKA at 15 V and the operating cathode current IKA at 50 mA, with recommended cathode current of 5 to 10 mA and minimum regulation current IK(MIN) of 0.6 to 1 mA. |
| 2 | R | passive | Reference input connected to the internal 1.25 V band-gap reference (VREF), with the reference input current IREF limited to 1 mA maximum. |
| 3 | A | passive | Anode terminal, the common return of the shunt regulator, which the datasheet's application circuits use as the reference node for the output voltage; no separate anode rating is given. |
