Overview
The LMV331ILT, manufactured by STMicroelectronics, is a single, low-voltage comparator that is part of the LMV3xx series. These devices are the low-voltage versions of the industry-standard LM339 and LM393 comparators. They are designed to operate with a supply voltage ranging from 2.7 to 5 V and exhibit lower current consumption compared to their predecessors. The LMV331ILT is ideal for low-voltage applications and is available in compact packages such as the SOT23-5, making it suitable for space-constrained designs. The device operates over a wide temperature range of -40°C to +125°C, ensuring reliability in various environmental conditions.
