NCP161ASN330T1G from onsemi, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input voltage supply pin. Operating range 1.9 V to 5.5 V; absolute max -0.3 V to 6 V. Bypass to GND with a 1 µF ceramic capacitor placed close to the pin. |
| 2 | GND | power_in | Common ground connection for the regulator and reference circuitry. |
| 3 | EN | input | Chip enable input. VEN < 0.4 V disables the regulator (shutdown current 0.01 µA typ.); VEN > 1.2 V enables the LDO. EN pull-down current 0.2 µA typ. at VEN = 4.8 V. Absolute max -0.3 V to 6 V. |
| 4 | NC | unconnected | No connect. Not internally bonded on the SOT23-5 package; leave floating or tie to GND. |
| 5 | OUT | power_out | Regulated output voltage (3.3 V fixed for the '330' option; ±2% accuracy). Requires a 1 µF ceramic output capacitor for stability. Output current up to 450 mA; current limit 450-700 mA typ. |
