NCP115ASN120T2G from onsemi, in a TSOP-5. 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 | IN | power_in | Input pin of the regulator, operating input voltage range 1.7 V to 5.5 V, with a small capacitor required from this pin to ground for stability. |
| 2 | GND | power_in | Power supply ground pin. |
| 3 | EN | input | Driving EN above 0.9 V turns on the regulator and driving it below 0.4 V puts it into shutdown mode, with an internal pull-down of typ. 300 nA that keeps the device off when EN is not connected. |
| 4 | N/C | unconnected | Not connected; this pin can be tied to ground to improve thermal dissipation. |
| 5 | OUT | power_out | Regulated output voltage pin, requiring a small ceramic capacitor with a minimum value of 1 µF from this pin to ground to assure stability. |
