LMV721AM5 from HGSEMI, in a SOT-23-5. 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	OUT	output	Op-amp output. Rail-to-rail swing, drives up to about 70 mA (typ) into the load; output impedance ~7.5 ohm at 100 kHz, G=1.
2	VSS	power_in	Negative supply / ground reference. Typically tied to GND in single-supply operation. Supply range VDD-VSS = 2.1 V to 5.5 V (absolute max 7.5 V).
3	IN+	input	Non-inverting analog input. Rail-to-rail common-mode range (-0.1 V to VDD+0.1 V typ at Vs=5.5 V). Input bias current ~1 pA (typ).
4	IN-	input	Inverting analog input. Rail-to-rail common-mode range. Input voltage must stay within Vss-0.5 V to VDD+0.5 V (absolute max).
5	VDD	power_in	Positive supply pin. Operating range 2.1 V to 5.5 V (VDD-VSS); absolute max 7.5 V. Quiescent current ~1.1 mA typ.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmv721am5.step`	85 KB	You want the bare part, or you mark your own boards.
`lmv721am5-etched.step`	1.3 MB	You want the part with `LMV721AM5` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 336 faces against 102 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.
