NCV4294CSN50T1G from onsemi, in a TSOP-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 | NC | unconnected | Not connected. Pin is not internally bonded and should be left floating or tied to ground for board routing convenience. |
| 2 | GND | power_in | Power supply ground. Connect to system ground; both GND pins (2 and 5) should be tied together at the device. |
| 3 | Vin | power_in | Unregulated positive power supply input, operating range Vout,nom + 0.5 V (or 3.5 V, whichever is higher) up to 45 V DC (60 V load-dump suppressed). Bypass with a 0.1 µF (100 nF) capacitor to ground. |
| 4 | Vout | power_out | Regulated positive output voltage (5.0 V for the -50 suffix, 3.3 V for the -33 suffix) at up to 30 mA. Requires a 2.2 µF output capacitor with ESR < 7 Ω to ground for stability. |
| 5 | GND | power_in | Power supply ground. Second ground pin; tie together with pin 2 at the device for lowest impedance return. |
