LM809M3-3.08 TI Supervisory Circuit | SOT-23-3 | 3.08V Threshold, Active-Low Reset

Product Overview

The LM809M3-3.08 is a supervisory circuit from Texas Instruments designed to monitor power supplies in microprocessor and digital systems. It provides a reset signal to the host processor when the supply voltage drops below a preset threshold of 3.08V, ensuring reliable system operation during power-up, power-down, and brownout conditions. Housed in a compact SOT-23-3 package, it is ideal for space-constrained applications.
