LPM3406B3F from LOWPOWER, 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 | Gate | input | Gate terminal of the N-channel MOSFET, used to switch the device (VGS limits are ±20 V per the absolute maximum ratings, not pin-specific). |
| 2 | Source | passive | Source terminal of the N-channel MOSFET, serving as the reference for the gate drive; the datasheet gives no pin-specific limit for this pin. |
| 3 | Drain | passive | Drain terminal of the N-channel MOSFET, carrying the switched current (VDS 30 V and continuous ID 3.6 A at TA=25℃ per the absolute maximum ratings, not pin-specific). |
