The 2.2-V supply voltage operation, 5.4-μA quiescent current, and 0.7-ms power-on time enable effective power-cycling architectures to minimize power consumption for battery-powered applications such as drones and sensor nodes. The LMT86LPG through-hole TO-92S package fast thermal time constant supports offboard time-temperature sensitive applications such as smoke and heat detectors. The accuracy over the wide operating range and other features make the LMT86 an excellent alternative to thermistors. For devices with different average sensor gains and comparable accuracy, refer to Comparable Alternative Devices for alternative devices in the LMT8x family.
