TPS3839L30DBZR TI Supervisory Circuit | SOT-23-3 | 2.63V Threshold, Active-Low Reset

Product Overview

The TPS3839L30DBZR from Texas Instruments is a precision voltage supervisor designed for monitoring supply voltages in microprocessor and digital systems. It features a fixed threshold voltage of 2.63V and provides an active-low reset output. The device is available in a compact SOT-23-3 package, making it ideal for space-constrained applications. With ultra-low quiescent current of 220 nA (typical), it is well-suited for battery-powered and portable devices. The reset output remains asserted for a minimum of 200 ms after VDD rises above the threshold, ensuring proper system initialization.
