LD1117S12TR-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 | Vss/ADJ | power_in | Ground reference pin (labelled Vss/ADJ on the pin drawing and Adj/GND in the block diagram); it is the adjust pin on the ADJ version, where an optional CADJ bypass capacitor to ground improves ripple rejection. |
| 2 | Vout | power_out | Regulated output pin (1.2V on the LD1117S12TR) delivering up to 1A maximum output current, with a 10uF tantalum output capacitor recommended for stability. |
| 3 | Vin | power_in | Unregulated supply input pin with operating range up to 15V max and an absolute maximum of 18V, with a 10uF tantalum bypass capacitor recommended. |
