LD1117S33TR-HXY from HXY MOSFET, 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 | power_in | Ground reference pin (labelled Vss/ADJ on the fixed-voltage pinout; Adj/GND in the block diagram, where it is the adjust pin on the ADJ version). |
| 2 | VOUT | power_out | Regulated output (3.3V ±2%, 3.234V to 3.366V for LD1117S33TR) delivering up to 800mA, with a 10uF tantalum output capacitor recommended for stability. |
| 3 | VIN | power_in | Input supply pin, absolute maximum 18V and recommended operating maximum 15V, with 10uF tantalum bypass capacitor recommended. |
