LN809C2641MR-G from NATLINEAR, in a SOT-23-3L. 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 | GND | power_in | Ground reference for the detector; the CMOS output goes to ground when VIN falls below the detect voltage VDF. |
| 2 | VDD | power_in | Supply input VIN with an operating range of 0.7 V to 6.0 V and an absolute maximum of 6 V; the detect voltage is monitored on this pin. |
| 3 | RESET | output | Reset output (CMOS push-pull for the C variant, so output is CMOS-compatible); it follows VIN and is held low for the internal delay (70 ms to 120 ms for delay code 1 in this MPN's code, 130 ms to 350 ms for code 4) after VIN recovers above VDR. |
