LN8541MR-G from NATLINEAR, in a SOT-23-5. 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 of the amplifier, rail-to-rail with output current of 18 to 23 mA as listed in the electrical table. |
| 2 | -Vs | power_in | Negative supply rail; the operating supply range is 2.1 V to 5.5 V and the absolute maximum operating voltage is 7.5 V. |
| 3 | +IN | input | Non-inverting input; common-mode input range is -0.1 V to 5.6 V at VS = 5.5 V, and absolute-maximum common-mode voltage is (-VS)-0.5 V to (+VS)+0.5 V. |
| 4 | -IN | input | Inverting input; same common-mode limits as +IN, with absolute-maximum common-mode voltage of (-VS)-0.5 V to (+VS)+0.5 V. |
| 5 | +Vs | power_in | Positive supply rail; the operating supply range is 2.1 V to 5.5 V and the absolute maximum operating voltage is 7.5 V. |
