TLV803RDBZR TI Supervisory Circuit | SOT-23-3 | 2.63V Threshold, Active-Low Reset

Product Overview

The TLV803RDBZR from Texas Instruments is a supervisory circuit designed to monitor power supplies in digital systems. It provides a reset output to the microprocessor during power-up, power-down, and brown-out conditions. The device operates over a wide voltage range and features a fixed-sense threshold voltage of 2.63V. The reset output remains active for a minimum of 140ms after VDD rises above the threshold, ensuring proper system initialization. Housed in a compact SOT-23-3 package, the TLV803RDBZR is ideal for space-constrained applications requiring reliable voltage monitoring.
