TS321IDBVR 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	OUT	output	Op-amp output. Sources up to 40 mA typical (VCC=15 V), sinks up to 20 mA typical; short-circuit protected to ground.
2	VCC-	power_in	Negative supply pin. Tie to GND for single-supply operation (3 V to 30 V) or to the negative rail for dual-supply operation (±1.5 V to ±15 V). Absolute max VCC(single)=32 V, VCC(dual)=±16 V.
3	IN+	input	Non-inverting op-amp input. Common-mode input range extends from VCC- to VCC+ - 1.5 V; typical input bias current 20 nA (out of the device).
4	IN-	input	Inverting op-amp input. Common-mode input range extends from VCC- to VCC+ - 1.5 V; differential input voltage abs-max ±32 V.
5	VCC+	power_in	Positive supply pin. Recommended 3 V to 30 V single-supply (or up to ±15 V dual). Typical total supply current 500 µA at VCC=5 V, no load.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ts321idbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`ts321idbvr-etched.step`	1.9 MB	You want the part with `TS321IDBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 468 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.
