NCP1117LPSTADT3G from onsemi, 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 | Adj (GND) | power_in | A resistor divider from this pin to the Vout pin and ground sets the output voltage on adjustable devices, and this pin is ground only for fixed-mode devices. |
| 2 | Vout | power_out | Regulator output that requires a minimum 10 µF capacitor with 20 mΩ ≤ ESR ≤ 20 Ω connected to ground for stability; the heatsink tab is also connected to this pin. |
| 3 | Vin | power_in | Input pin that is typically bypassed with a large storage capacitor (20 mΩ ≤ ESR ≤ 20 Ω) and must always be 1.3 V (typ.) higher than Vout for proper regulation; DC input is rated −0.3 to 18 V. |
