LMV331TP-MS

The LMV331TP-MS is MSKSEMI's single low-voltage comparator in SOT-23-5. It operates from +2.1 V to +5.5 V, draws a low supply current of 50 uA typical per channel at 5 V with the output low, accepts an input common-mode range that includes ground, and saturates at about 100 mV typical. The open-drain output is pulled up externally, so the comparison result can be level-shifted to the logic rail of the MCU or controller reading it - the arrangement MSKSEMI's application material recommends for threshold alarms, window detection and level translation in portable and industrial equipment. Brand clarity matters on this page: LMV331TP-MS is the MSKSEMI device, specified by MSKSEMI's own datasheet. A nearly identical base name, LMV331TP-TR, is sold by 3PEAK with a different datasheet and a wider 1.8 V minimum supply; the two are separate manufacturers' parts that share a functional class and package style, not interchangeable order codes. Selection advice: quote the complete LMV331TP-MS string including the -MS suffix, verify the 2.1 V lower supply limit against your rail (designs that must run down to 1.8 V belong on the other maker's page), and confirm pinout against the MSKSEMI datasheet before layout release. Parameters verified against MSKSEMI documentation.
