TLV431ILPR from Texas Instruments, in a TO-92-3. 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 | CATHODE | output | Shunt regulated output; voltage adjustable from 1.24 V to 6 V with external resistor network; absolute maximum continuous cathode current ±20 mA. |
| 2 | ANODE | power_in | Ground return; common pin normally connected to negative supply rail or circuit ground. |
| 3 | REF | input | Reference input pin; voltage applied from external resistor divider between cathode and anode; requires minimum input current 0.5 µA per datasheet Section 5.5. |
