LM4041BIDBZR 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 | FB | input | Feedback pin for the adjustable output voltage, set by an external resistor divider to any value from 1.225 V to 10 V; the feedback pin is rated at 1 kV HBM ESD. |
| 2 | Cathode | bidirectional | Shunt current and output voltage pin; continuous cathode current is rated -10 mA to 25 mA absolute maximum, with 12 mA stated as the maximum recommended cathode current. |
| 3 | Anode | power_in | Anode pin, normally grounded; the datasheet's table labels it as an output (O), but it is the reference's return/ground connection. |
