LMV331-MS from MSKSEMI, 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 | +IN | input | Noninverting input of the comparator; the input common-mode range includes ground (V-), per the electrical characteristics. |
| 2 | V- | power_in | Negative (lowest) power supply pin; in single-supply use it is tied to ground. |
| 3 | -IN | input | Inverting input of the comparator. |
| 4 | OUT | output | Open-drain comparator output, which needs an external pull-up resistor to set the logic-high level (pull-up voltage range up to 5.6 V, sinking up to 50 mA at VO ≤ 1.5 V at 5 V supply). |
| 5 | V+ | power_in | Positive (highest) power supply pin; operating supply range is 2.1 V to 5.5 V. |
