LMV331SE-7 from Diodes Incorporated, in a SOT-353. 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 | Non-inverting comparator input; the common-mode input voltage range extends from -0.1 V below the negative supply to within 0.8 V of the positive supply. |
| 2 | VEE | power_in | Negative chip supply voltage, also used as GND; the device operates from a single supply of 2.7 V to 5.5 V (VCC-VEE). |
| 3 | IN- | input | Inverting comparator input. |
| 4 | OUT | output | Open-collector output that requires an external pull-up resistor to the positive supply, recommended between 1 kΩ and 10 kΩ. |
| 5 | VCC | power_in | Positive chip supply voltage, specified at 2.7 V to 5.5 V relative to VEE; a 0.1 µF bypass capacitor should be placed as close as possible between VCC and GND. |
