Overview
The TLV803EA26DBZR is a low-power voltage supervisor from Texas Instruments, designed to monitor the voltage level of the supply voltage (VDD) and provide a reset signal when the voltage falls below a specified threshold. This device is part of the TLV803E, TLV809E, and TLV810E family, which are enhanced alternatives to earlier voltage supervisors like the TLV803, TLV853, and LM809. The TLV803EA26DBZR features a low quiescent current, high accuracy, and a wide operating temperature range, making it suitable for various applications requiring reliable voltage monitoring.
