AMS1117T-ADJG from HANSCHIP semiconductor, in a TO-220-3. 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 | GND/ADJ | power_in | Ground / adjust pin; on the adjustable (ADJ) version it sets the output voltage, with adjust-pin current typically 60 µA and at most 120 µA (Iadj). |
| 2 | VOUT | power_out | Regulated output voltage; for the adjustable version the output needs at least a 22 µF tantalum capacitor for stability, and dropout is 1.20 V typical at 800 mA. |
| 3 | VIN | power_in | Input supply voltage; absolute maximum is 15 V and recommended operating input voltage is 12 V maximum, with the regulator operating from junction temperature -40 °C to +125 °C. |
