LM4041CEM3-ADJ 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, which the datasheet states can be set from 1.24 V to 10 V by an external resistor divider (VO = VREF[(R2/R1)+1]); the pin can also be driven from an external voltage in open-loop comparator mode. |
| 2 | - | bidirectional | Negative terminal (cathode) that shunts current and sets the output voltage; the recommended reverse current is 60 µA to 12 mA, with an absolute maximum reverse current of 20 mA and an absolute maximum output voltage of 15 V. |
| 3 | + | power_in | Positive terminal (anode), normally grounded, with an absolute maximum forward current of 10 mA. |
