LTA180A1XT5 from Linearin(先积集成), in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Output voltage, with a range that extends to within millivolts of each supply rail. |
| 2 | GND | power_in | Negative power supply (ground). |
| 3 | IN+ | input | Positive current-sense input, connected to the bus-voltage side of the sense resistor for high-side sensing, with common-mode range of -0.2 V to +26 V. |
| 4 | IN- | input | Negative current-sense input, connected to the load side of the sense resistor for high-side sensing, with common-mode range of -0.2 V to +26 V. |
| 5 | VS | power_in | Positive power supply, typically 2.7 V to 5.5 V, with a 0.1 uF bypass capacitor to GND placed close to the pin. |
