NCV303LSN30T1G 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 | Reset Output | output | Active-low reset output of the NCP303 open-drain N-channel stage, with a maximum output voltage of −0.3 to 12 V and a maximum output current of 70 mA. |
| 2 | Input | input | Monitored supply voltage input (Vin), with a maximum input power supply voltage of 12 V. |
| 3 | N.C. | unconnected | Not connected; the pin connection table lists this pin as N.C. (see review note on the block diagram). |
| 4 | Ground | power_in | Ground reference pin for the device. |
| 5 | CD | passive | Delay capacitor pin, with a pin voltage limited to −0.3 V to Vin + 0.3 V; the internal CD pull-up is about 1.0 MΩ and the power-good delay is estimated as tD2 ≈ RD × CD. |
