LMV821M5X from Texas Instruments, 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	OUTPUT	output	Op-amp output. Rail-to-rail output (RRO) - swings within ~55 mV of the supply rails with a 10 kΩ load and within ~160 mV with a 600 Ω load. Continuous output current should be kept below 45 mA for long-term reliability.
2	V-	power_in	Negative supply rail. Tied to ground for single-supply operation; can be a negative rail for split-supply operation. Total supply (V+ − V-) range is 2.5 V to 5.5 V; absolute max 5.5 V.
3	+IN	input	Non-inverting input. Common-mode input range is -0.3 V to 4.3 V at Vs = 5 V. Input bias current typically 30 nA, offset voltage typically 1 mV (3.5 mV max).
4	-IN	input	Inverting input. Same common-mode range and input specs as +IN. CMRR typically 90 dB, PSRR typically 85 dB.
5	V+	power_in	Positive supply rail. Operates from 2.5 V to 5.5 V (absolute max 5.5 V). Quiescent current is typically 220 µA per amplifier.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmv821m5x.step`	85 KB	You want the bare part, or you mark your own boards.
`lmv821m5x-etched.step`	1.5 MB	You want the part with `LMV821M5X` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 388 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.
