GN1117-3.3V from GN Semic, in a SOT-223-3L. 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 | ADJ/GND | power_in | Pin labelled ADJ/GND in the datasheet pin table (可调端/地, adjustable terminal/ground); it is the adjust terminal for the GN1117-ADJ and the ground connection for the fixed-voltage versions. |
| 2 | VOUT | power_out | Regulated output terminal; the datasheet gives a maximum output current of 1 A (IOMAX at VIN-VOUT=2V, 1.2 A typical limit) and a dropout of 1.45 V typical to 1.65 V maximum at IOUT=1 A. |
| 3 | VIN | power_in | Input terminal; the recommended input voltage is 2.75 V to 15 V and the absolute maximum supply voltage is 18 V. |
