TPS3840PL30DBVR TI Voltage Supervisor | SOT-23-5 | 3.0V Threshold, Active-Low

Product Overview

The TPS3840PL30DBVR from Texas Instruments is a high-accuracy voltage supervisor designed for monitoring power supply voltages in a wide range of applications. Housed in a compact SOT-23-5 package, this device offers a fixed threshold voltage of 3.0V with a precision of ±1.5% over temperature. It features an active-low, open-drain reset output that remains asserted when VDD drops below the threshold and for a fixed delay time after VDD rises above it. The TPS3840PL30DBVR is ideal for systems requiring reliable power-on reset and voltage monitoring, with ultra-low quiescent current of typically 0.5 µA, making it suitable for battery-powered applications.
