TPTLVH431BIDCKR 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) terminal of the shunt regulator. Sinks the programmed cathode current I_KA (0.1-100 mA operating, absolute max -100 to +150 mA). Maximum cathode voltage V_KA = 18 V referenced to anode. |
| 2 | NC | unconnected | No internal connection. Per datasheet note, pin 2 is attached to substrate and must be connected to ANODE or left open. |
| 3 | REF | input | Reference input to the internal error amplifier. Regulates V_KA so that V_REF ≈ 1.24 V (1.234-1.246 V) appears at this pin. Reference input current typ 0.7 µA (max 4 µA); absolute max reference input current 10 mA. |
| 4 | NC | unconnected | No internal connection. Per datasheet note, pin 4 is attached to substrate and must be connected to ANODE or left open. |
| 5 | NC | unconnected | No internal connection. Per datasheet note, pin 5 is attached to substrate and must be connected to ANODE or left open. |
| 6 | ANODE | passive | Anode (A) terminal of the shunt regulator; the ground/return reference for V_KA and V_REF. All voltages are referenced to this pin. |
