NCP161AMX330TBG from onsemi, in a XDFN-4-EP(1x1). 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 | OUT | power_out | Regulated output voltage; the output should be bypassed with a small 1 µF ceramic capacitor. |
| 2 | GND | power_in | Common ground connection. |
| 3 | EN | input | Chip enable: applying VEN < 0.4 V disables the regulator, and pulling VEN > 1.2 V enables the LDO. |
| 4 | IN | power_in | Input voltage supply pin; absolute maximum input voltage is -0.3 V to 6 V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
