LM1117S-5.0 from HTC Korea TAEJIN Tech, in a SOT-223-3. 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 | Adjustable/ground pin; the datasheet lists this pin as Adjustable / Ground, and for the fixed 5.0V part it serves as the ground connection. |
| 2 | VOUT | power_out | Regulated output voltage pin; the datasheet requires an output capacitor of 10 µF or larger for output stability. |
| 3 | VIN | power_in | Input voltage pin; the maximum DC input voltage is 20 V (absolute maximum rating), and the operating input voltage is listed as 12 V in the electrical characteristics. |
