AMS1117DCY-ADJRG from HANSCHIP semiconductor, 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 | GND/ADJ | power_in | Ground reference for the fixed-output versions and the adjust terminal for the ADJ version, with no separate voltage or current limit stated for this pin in the datasheet. |
| 2 | VOUT | power_out | Regulated output voltage; the ADJ version needs an output capacitor of at least 22 µF tantalum for stability, and stability falls as output current increases. |
| 3 | VIN | power_in | Unregulated input supply, with an absolute maximum of 15 V and a recommended operating input voltage of 12 V, and the dropout is 1.2 V at 800 mA output current. |
