LP3986-30B3F from LOWPOWER, in a SOT-23. 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 | GND | power_in | Ground reference for the regulator. |
| 2 | OUT | power_out | Regulated 3.0V output pin. Requires a 2.2µF low-ESR ceramic output capacitor to GND. Sources up to 300mA with typical current limit of 350mA. |
| 3 | VIN | power_in | Power input pin. Operating supply range 2.5V to 6V (absolute max 7V). Requires a 2.2µF input capacitor to GND. |
