TPS3809L30DBVT TI Voltage Supervisor | SOT-23-3 | 3.0V Threshold, Active-Low Reset

Product Overview

The TPS3809L30DBVT from Texas Instruments is a low-power, precision voltage supervisor designed for monitoring 3.0V supply voltages. Housed in a compact SOT-23-3 package, it provides a reset output that remains active-low until the supply voltage stabilizes above the threshold. With a typical quiescent current of only 2.2 µA, it is ideal for battery-powered and portable applications. The device features a fixed threshold voltage of 3.0V with ±2% accuracy over temperature, ensuring reliable system reset during power-up, power-down, and brown-out conditions.
