LGS6302B5 from Legend Si, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Internal power switch node. Connect to external inductor and Schottky diode. |
| 2 | GND | power_in | Ground. |
| 3 | FB | input | Feedback input. Connect to external resistors to set output voltage. |
| 4 | EN | input | Enable pin. Drive high (>0.6V) to enable, low (<0.3V) to disable. |
| 5 | VIN | power_in | Power input. Bypass with ≥4.7µF ceramic capacitor near VIN and GND. |
