AMS1117KTP-3.3RG from HANSCHIP semiconductor, in a TO-252. 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 pin for the fixed 3.3V version; the datasheet labels it GND/ADJ, and the ADJ function applies only to the adjustable version. |
| 2 | VOUT | power_out | Regulated output voltage, specified at 3.3 V with a 3.250 V to 3.365 V range at 10 mA load, and rated for output current up to 800 mA. |
| 3 | VIN | power_in | Input operating voltage with an absolute maximum of 15 V and a recommended input voltage of up to 12 V. |
