LM4051CIM3X-ADJ from Texas Instruments, in a SOT-23-3. 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 | FB | input | Feedback input referenced to the cathode (pin 2); with the external R1/R2 divider it sets the LM4051-ADJ output from 1.24 V to 10 V, and the output must stay below the 15 V absolute maximum. |
| 2 | Cathode | bidirectional | Shunt current/voltage terminal of the reference; the series resistor RS sets the reverse current, which must stay between the 60 µA minimum and 12 mA maximum (absolute maximum reverse current 20 mA). |
| 3 | Anode | passive | Common (-) reference pin, usually grounded; on the SOT-23 package this pin is also the (-) output connected through the die, so it must be used as the common return. |
