TLV431BQDBZRQ1 from Texas Instruments, 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 | REF | input | Reference voltage input terminal relative to anode; external resistor divider network connected to this pin sets the regulated output voltage. |
| 2 | CATHODE | output | Shunt cathode regulated output terminal with output voltage range from VREF (1.24V nominal) to 6V and continuous current rating of ±20mA. |
| 3 | ANODE | power_in | Common anode ground reference terminal and internal substrate connection point typically connected to ground. |
