TLV803EA42RDBZR TI Supervisory Circuit | SOT-23-3 | 4.2V Threshold, Active-Low Reset

Product Overview

The TLV803EA42RDBZR from Texas Instruments is a supervisory circuit designed to monitor power supply voltages in digital systems. It provides a reset output to the microprocessor during power-up, power-down, and brown-out conditions. The device features a fixed threshold voltage of 4.2V and an active-low, open-drain reset output. Housed in a compact SOT-23-3 package, it is ideal for space-constrained applications requiring reliable voltage monitoring.
