LM809M3X-3.08/NOPB TI Supervisory Circuit | SOT-23-3 | 3.08V Threshold, Active-Low Reset

Product Overview

The LM809M3X-3.08/NOPB is a supervisory circuit from Texas Instruments designed to monitor power supplies in microprocessor-based systems. It provides a reset output during power-up, power-down, and brownout conditions. The device features a fixed 3.08V threshold voltage and an active-low reset output. It is available in a compact SOT-23-3 package, making it suitable for space-constrained applications. The LM809M3X-3.08/NOPB ensures reliable system operation by preventing code execution errors during voltage transients.
