AMS1117-5.0V from MSKSEMI, in a SOT-89. 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 | VSS/ADJ | power_in | VSS/ADJ pin, the ground/adjust connection; on the adjustable version it sets the output voltage through the external resistor divider, with adjust pin current specified at 55 to 120 µA. |
| 2 | VOUT | power_out | Output voltage pin delivering the regulated output, 5.0V for this fixed version, with load current up to 1A. |
| 3 | VIN | power_in | Input voltage pin; the datasheet gives an operating input range up to 15V and an absolute maximum input voltage of 18V. |
