Diodes Incorporated · Monitors & Reset Circuits · SOT-23

APX803L05-44SA-7 from Diodes Incorporated, 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 GND power_in Ground.
2 RESET output Active-low open-drain reset output, pulled low when VCC falls below the threshold; output voltage rated 0 to 5.5V recommended (-0.3 to 6.0V absolute maximum) and VOL max 0.4V at 3.5mA sink.
3 VCC power_in Operating voltage input and monitored supply, recommended 0.9V to 5.5V (absolute maximum -0.3 to 6.0V).
