LN809C2941MR-G

NATLINEAR · Supervisor and Reset ICs · SOT-23-3L

LN809C2941MR-G from NATLINEAR, in a SOT-23-3L. 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 GND power_in Ground / VSS reference for the detector. Connect to system ground.
2 RESET output Reset output. For the 'C' variant this is a CMOS push-pull output that follows VIN when VIN ≥ VDR, and is pulled to VSS when VIN < VDF plus the built-in delay (tDLY = 130-350 ms on the '4' delay option). IOUT rated to 50 mA absolute max.
3 VDD power_in Supply / monitored input voltage (VIN). Operating range 0.7 V to 6.0 V; absolute max 6 V. Also serves as the sensed rail for the VDF = 2.93 V detect threshold in this variant. Typical ISS ≈ 1.0-1.2 µA.
