LN709C2641VR-G from NATLINEAR, in a SOT-23. 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 | VSS | power_in | Ground pin of the voltage detector. |
| 2 | VOUT | output | CMOS detector output, equal to VIN when VIN is above the release voltage after the built-in delay and pulled to ground when VIN falls below VDF; absolute maximum -0.3 to VIN+0.3 V, 20 mA. |
| 3 | VIN | power_in | Supply and voltage-sense input, operating range 0.7 V to 6.0 V (absolute maximum 6 V). |
