SPX1117M3-L-1-5 from MaxLinear, in a SOT-223-3. 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 | power_in | Ground pin on the fixed 1.5V version (labelled ADJ/GND; it is the adjust pin only on the adjustable version). |
| 2 | VOUT | power_out | Regulated 1.5V output (1.485V to 1.515V at 25°C, 5mA load), rated for 800mA guaranteed output current; the tab is also connected to VOUT. |
| 3 | VIN | power_in | Input supply, absolute maximum 20V, with a dropout voltage of 1.1V typical at 800mA. |
