Key Featrues

High Accuracy: The LMT87 offers a typical accuracy of ±0.4°C (±2.7°C maximum), ensuring precise temperature measurements. This high accuracy is crucial for applications requiring reliable thermal monitoring, such as medical devices and industrial systems.
Low Power Consumption: With a quiescent current of just 5.4 µA and a 2.7-V supply voltage, the LMT87 is ideal for battery-powered applications like drones and sensor nodes, significantly extending battery life.
Fast Thermal Time Constant: The LMT87LPG (TO-92S package) features a fast thermal time constant of 10 seconds (typical with 1.2 m/s airflow), making it suitable for time-sensitive applications such as smoke and heat detectors.
Linear Analog Output: The sensor provides a linear analog output voltage inversely proportional to temperature with a gain of -13.6 mV/°C, simplifying temperature measurement and integration into existing systems.
Industry-Standard Footprint: The LMT87 is footprint-compatible with the LM20/19 and LM35 temperature sensors, allowing for easy replacement or upgrades in existing designs without requiring significant hardware changes.

Applications

Battery-Powered IoT Devices: The LMT87 is ideal for battery-powered IoT devices such as drones and sensor nodes due to its low 2.7-V operation, 5.4-µA quiescent current, and 0.7-ms power-on time. Its precision and low power consumption make it suitable for applications requiring accurate temperature monitoring while maximizing battery life.
Smoke and Heat Detectors: The LMT87LPG (TO-92S package) is well-suited for smoke and heat detectors due to its fast thermal time constant of 10 seconds typical (1.2 m/s airflow). Its wide temperature range (-50°C to 150°C) and high accuracy (±0.4°C typical) ensure reliable performance in critical safety applications.
Industrial Temperature Monitoring: The LMT87 is an excellent choice for industrial temperature monitoring systems, offering a linear analog output voltage inversely proportional to temperature. Its ±2.7°C maximum accuracy and -13.6 mV/°C gain make it a cost-effective alternative to thermistors for precise temperature control in industrial environments.
Consumer Electronics: The LMT87 is suitable for consumer electronics applications, such as smart home devices and wearables, due to its small package options (SOT-SC70, TO-92) and compatibility with industry-standard LM20/19 and LM35 temperature sensors. Its low power consumption and high accuracy make it ideal for compact, energy-efficient designs.
