The 1.5-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 LMT84LPG 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 LMT84 an excellent alternative to thermistors. For device...
