LM809M3-2.63/NOPB TI Supervisor Circuit | SOT-23-3 | 2.63V Threshold, Active-Low Reset

Product Overview

The LM809M3-2.63/NOPB is a supervisory circuit from Texas Instruments (TI) designed to monitor power supplies in microprocessor and digital systems. It provides a reset signal to the system during power-up, power-down, and brown-out conditions. The device features a fixed threshold voltage of 2.63V, ensuring reliable operation with 3V, 3.3V, and 5V power supplies. Housed in a compact SOT-23-3 package, it is ideal for space-constrained applications. The reset output is active-low and remains asserted for a minimum of 140ms after VCC rises above the reset threshold, allowing the system to stabilize.
