AMS1117-5.0RG from HANSCHIP semiconductor, in a SOT-223. 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 | GND/ADJ | power_in | Ground for the fixed-voltage versions and the adjust pin for the adjustable version (datasheet lists it as 地/ADJ). |
| 2 | VOUT | power_out | Regulated output voltage; the adjustable version requires at least a 22 µF tantalum output capacitor for stability, while fixed versions may use smaller capacitors. |
| 3 | VIN | power_in | Input supply voltage; the absolute maximum input is 15 V and the recommended input voltage is 12 V. |
