NCP500SN25T1G from onsemi, in a TSOP-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 | Vin | power_in | Positive power supply input voltage, rated 0 to 6.0 V maximum with a 1.8 V to 6.0 V operating range. |
| 2 | GND | power_in | Power supply ground. |
| 3 | Enable | input | Places the device into low-power standby when pulled to a logic low (disabled), and should be connected to Vin if the function is not used. |
| 4 | N/C | unconnected | No internal connection. |
| 5 | Vout | power_out | Regulated output voltage (2.5 V nominal for this part), requiring a minimum 1.0 uF output capacitor. |
