**TECH PUBLIC** · Comparators · SOT23-5

LMV331W5 from TECH PUBLIC, in a SOT23-5. 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 | Non-inverting comparator input; analog input voltage range is Vss-0.5V to VDD+0.5V (absolute maximum). |
| 2 | VSS | power_in | Negative supply / ground; VDD to Vss absolute maximum is 7V. |
| 3 | IN- | input | Inverting comparator input; analog input voltage range is Vss-0.5V to VDD+0.5V (absolute maximum). |
| 4 | OUT | output | Open-drain comparator output. |
| 5 | VDD | power_in | Positive supply; operating range 1.8V to 5.5V, absolute maximum 7V above Vss. |
