TLV803EC43DBZR TI Supervisory Circuit | SOT-23-3 | 4.38V Threshold, Active-Low Reset

Product Overview

The TLV803EC43DBZR from Texas Instruments is a supervisory circuit designed to monitor power supplies in digital systems. It provides a reset signal to the host processor when the supply voltage drops below a preset threshold, ensuring reliable system operation during power-up, power-down, and brown-out conditions. Housed in a compact SOT-23-3 package, this device is ideal for space-constrained applications requiring precise voltage monitoring and low power consumption.
