NCP718BSN330T1G 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. |
| 2 | GND | power_in | Power supply ground. |
| 3 | EN | input | Enable pin: driving it high turns the regulator on and driving it low puts the regulator into shutdown mode; VEN_HI is 1.2 V minimum and VEN_LO is 0.4 V maximum. |
| 4 | NC/ADJ | unconnected | Fixed version (this NCP718BSN330T1G is a fixed 3.3 V part): no connection, which 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. |
