INA180A3IDBVR 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	Analog output voltage. V_OUT = 100 × (V_IN+ - V_IN-) + V_REF(GND). Swings rail-to-rail within (V_S - 0.03) V of V_S and (GND + 0.005) V of ground with a 10 kΩ load; slew rate 2 V/µs.
2	GND	power_in	Analog ground reference for the amplifier and output stage. Sets the zero-current reference level of OUT.
3	IN+	input	Current-sense amplifier positive (non-inverting) input. For high-side sensing, connect to the bus-voltage side of the sense resistor; for low-side sensing, connect to the load side. Common-mode range -0.2 V to +26 V, independent of V_S.
4	IN-	input	Current-sense amplifier negative (inverting) input. For high-side sensing, connect to the load side of the sense resistor; for low-side sensing, connect to the ground side. Common-mode range -0.2 V to +26 V.
5	VS	power_in	Positive supply voltage, 2.7 V to 5.5 V. Bypass to GND with a 0.1 µF ceramic capacitor placed close to the pin. Quiescent current 260 µA typical.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ina180a3idbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`ina180a3idbvr-etched.step`	2.2 MB	You want the part with `INA180A3IDBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 564 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.
