Overview
The LMV331ILT is a single-channel low-voltage comparator from STMicroelectronics, part of the LMV331 series. It operates within a supply voltage range of 2.7 V to 5 V and features an open-drain output type. The device exhibits a typical propagation delay of 200 ns and a low current consumption of 20 μA. Input common mode range includes ground, with a maximum input offset voltage of 7 mV at 5 V. It supports a maximum output current of 93 mA and functions across a temperature range of -40°C to +85°C. The component is housed in a SOT-23-5 surface-mount package.
Feature Summary
- Low power operation with minimal current consumption suitable for battery-powered systems
- Single-channel design with open-drain output capability for flexible interfacing
- Compact SOT-23-5 packaging optimized for space-constrained applications
Applications
- Low-voltage signal conditioning circuits
- Battery-operated electronic devices
- Space-constrained embedded systems
Procurement Notes
Verify the specific suffix ILT corresponds to the SOT-23-5 package and reel/cut-tape availability when sourcing. Confirm that the operating temperature range meets the -40°C to +85°C requirement for the target environment. Ensure compatibility with 2.7 V to 5 V supply rails. Check for RoHS compliance status as per manufacturer documentation before finalizing procurement.
Selection Notes
Select this component for applications requiring a single comparator with low quiescent current. The open-drain output requires an external pull-up resistor. Consider the 200 ns propagation delay for timing-sensitive designs. The SOT-23-5 package limits thermal dissipation compared to larger footprints. Verify input common-mode voltage ranges include ground potential for proper operation.
Part Context
The LMV331 is the single-channel version of the LMV3xx family, which also includes the dual LMV393 and quad LMV339. These devices serve as low-voltage counterparts to the industry-standard LM339 and LM393. The family shares similar electrical characteristics but differs in channel count and package options. This series is designed for general-purpose comparison tasks in modern low-voltage electronics.
Replacement Considerations
LMV331ICT is a compatible alternative in SC-70-5 packaging.
