INA180A3QDBVRQ1 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. Output = gain (100V/V for the A3 variant) × (V_IN+ − V_IN−). Drive capability limited to about 8 mA; swings within GND−0.3V to VS+0.3V.
2	GND	power_in	Analog ground reference for the amplifier.
3	IN+	input	Current-sense amplifier positive input. In high-side applications, connect to the bus-voltage side of the shunt resistor; in low-side applications, connect to the load side of the shunt. Common-mode range -0.2V to +26V.
4	IN-	input	Current-sense amplifier negative input. In high-side applications, connect to the load side of the shunt; in low-side applications, connect to the ground side of the shunt. Common-mode range -0.2V to +26V.
5	VS	power_in	Positive supply, 2.7V to 5.5V (6V absolute max). Bypass with 0.1 µF to GND close to the pin. Independent of the sensed bus voltage.
