MAX809L from TECH PUBLIC, in a SOT-23. 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 return pin. Connect to the system 0 V reference.
2	RESET	output	Active-low reset output (push-pull). Goes low when VDD falls below the reset threshold (V_RST = 4.63 V typ for L variant) and remains low for at least 140 ms after VDD rises back above V_RST. Output drive: sinks 1.5-5 mA at V_OL ≤ 0.3 V and sources 1.2-2.5 mA at V_OH ≥ VDD−0.4 V depending on VDD.
3	VDD	power_in	Chip supply and monitored voltage input. Operating range 1.0 V to 5.5 V (abs max 6.0 V). Typical supply current 8 µA at 2 V, 10 µA at 3 V, 14 µA at 5 V. Slew-rate limit 100 V/s.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`max809l.step`	59 KB	You want the bare part, or you mark your own boards.
`max809l-etched.step`	1.3 MB	You want the part with `MAX809L` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 333 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
