Overview
The TLV803EA29RDBZR is a low-power voltage supervisory circuit produced by Texas Instruments. It is part of the TLV80xE and TLV81xE family, which offers enhanced alternatives to earlier voltage supervisors like the TLV803, TLV853, TLV809, LM809, TPS3809, and TLV810. These devices are designed to monitor the VDD voltage level and initiate a reset signal when the supply voltage drops below a factory-programmed threshold. They are known for their low quiescent current, high accuracy, and wide temperature range, making them ideal for use in low-power and portable applications.
