TLVH431AQDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 | NC | unconnected | No internal connection. |
| 2 | * | passive | Pin 2 is attached to the substrate and must be connected to ANODE or left open. |
| 3 | CATHODE | passive | Cathode of the shunt regulator, operating from VREF up to 18 V (20 V absolute maximum) with 0.1 mA to 70 mA continuous cathode current. |
| 4 | REF | input | Reference input that sets the output voltage with an external resistor divider against the 1.24 V internal reference. |
| 5 | ANODE | power_in | Anode of the shunt regulator, normally connected to ground, with cathode voltage specified with respect to it. |
