NCP718ASN330T1G from onsemi, in a TSOT-23-5. 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; a small capacitor is needed from this pin to ground to assure stability, and the operating input voltage range is 2.5 V to 24 V. |
| 2 | GND | power_in | Power supply ground pin for the regulator. |
| 3 | EN | input | Enable pin: driving it high (at least 1.2 V) turns on the regulator and driving it low (at most 0.4 V) puts the regulator into shutdown mode. |
| 4 | NC/ADJ | unconnected | On the fixed-voltage version this pin is no connection and may be tied to ground to improve thermal dissipation or left disconnected. |
| 5 | OUT | power_out | Regulated output voltage pin; a small 1 µF ceramic capacitor is needed from this pin to ground to assure stability. |
