**onsemi** · Linear Voltage Regulators (LDO) · MSOP-8

NCP3335ADM330R2G from onsemi, in a MSOP-8. 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 | Vout | power_out | Regulated output voltage; bypass to ground with Cout ≥ 1.0 µF. |
| 2 | Vout | power_out | Regulated output voltage; bypass to ground with Cout ≥ 1.0 µF (tied with pin 1). |
| 3 | SENSE | input | Output voltage sensing pin; connect to pins 1 and 2. |
| 4 | GND | power_in | Power supply ground. |
| 5 | NR | passive | Optional noise reduction pin; a 10 nF capacitor to ground further reduces output noise, and it can be left unconnected. |
| 6 | SD | input | Shutdown pin (on above 2.0 V, off below 0.4 V); when not in use, connect to the input pin. |
| 7 | Vin | power_in | Power supply input voltage (2.6 V to 12 V supply range); tied with pin 8. |
| 8 | Vin | power_in | Power supply input voltage (2.6 V to 12 V supply range); tied with pin 7. |
