TP431C124C6 from TECH PUBLIC, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CATHODE | passive | Cathode (K) of the shunt reference. Sinks the regulated cathode current IKA (0.1-100 mA operating, 18 V absolute max VKA). Tied to the output node in shunt/series-regulator applications. |
| 2 | NC | unconnected | No internal connection. Attached to substrate; per datasheet note must be connected to ANODE or left open. |
| 3 | REF | input | Reference input (feedback) pin. Internal error amplifier regulates so that V(REF) ≈ Vref (typ 1.24 V). Driven by the R1/R2 divider from CATHODE to ANODE. Reference input current IREF ≈ 0.7 µA typ. |
| 4 | NC | unconnected | No internal connection. Attached to substrate; per datasheet note must be connected to ANODE or left open. |
| 5 | NC | unconnected | No internal connection. Attached to substrate; per datasheet note must be connected to ANODE or left open. |
| 6 | ANODE | passive | Anode (A) of the shunt reference. All voltage measurements are referenced to this pin; typically tied to circuit ground in shunt/series-regulator applications. |
