TLV431BIDCKR-TP 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 regulator. Sinks the regulated current (IKA 0.1-100 mA, absolute max 150 mA). VKA absolute maximum 18 V referenced to ANODE. Tied through a series resistor RB to the supply in typical shunt/series-regulator use. |
| 2 | NC | unconnected | No internal electrical connection. Pin is attached to the die substrate and must be left open or tied to ANODE. |
| 3 | REF | input | Reference input to the internal error amplifier. Regulation drives VKA so that V(REF) = Vref (~1.24 V typ). Typically connected to the R1/R2 divider from CATHODE to ANODE; reference input current IREF ~0.7 µA typ (4 µA max), absolute max 10 mA. |
| 4 | NC | unconnected | No internal electrical connection. Pin is attached to the die substrate and must be left open or tied to ANODE. |
| 5 | NC | unconnected | No internal electrical connection. Pin is attached to the die substrate and must be left open or tied to ANODE. |
| 6 | ANODE | passive | Anode (A) of the shunt regulator, the voltage-reference return terminal. All device voltages are specified with respect to this pin; connect to circuit ground / low side of the R1/R2 divider. |
