NCV1117STAT3G from onsemi, 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 | Adjust/Ground | power_in | Adjust pin of the adjustable device; it sets the output with R1 and R2, with adjust pin current typically 52 µA and at most 120 µA at Vin = 11.25 V and Iout = 800 mA. |
| 2 | Output | power_out | Regulated output, with the heatsink tab connected to this pin; a minimum 4.7 µF output capacitor with ESR between 33 mΩ (typ) and 2.2 Ω is required for stability. |
| 3 | Input | power_in | Unregulated input supply, rated for a maximum input voltage of 20 V. |
