Procurement Notes
Verify the specific ordering suffix matches the required packaging format. Confirm that the component meets RoHS3 and REACH compliance standards for your region. Ensure the selected variant aligns with the necessary thermal resistance characteristics for your PCB layout. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency before finalizing procurement orders.
Selection Notes
Select this component when space constraints require a compact SOT-25 footprint. Choose this part for designs requiring low quiescent current consumption below standard industry benchmarks. Consider this device for applications needing input signals referenced to ground. Verify that the open-collector output architecture fits the downstream circuit requirements without additional pull-up components.
Part Context
This device belongs to the LMV3xx series, which serves as the low-voltage counterpart to the industry-standard LM339 and LM393 comparators. While the LMV339 offers quad channels and the LMV393 provides dual channels, the LMV331 focuses on single-channel efficiency. The series maintains compatibility with existing designs while reducing power consumption and physical size.
