TPS3840PL27DBVR TI Voltage Supervisor | SOT-23-5 | 2.7V Threshold, 1.5% Accuracy

Product Overview

The TPS3840PL27DBVR from Texas Instruments is a high-accuracy voltage supervisor designed for monitoring power supply voltages in a wide range of applications. This device features a fixed threshold voltage of 2.7V with a precision of 1.5%, ensuring reliable system reset during power-up, power-down, and brown-out conditions. Housed in a compact SOT-23-5 package, it is ideal for space-constrained designs. The TPS3840PL27DBVR offers low quiescent current (typically 1.5 µA) and a programmable delay time via an external capacitor, making it suitable for battery-powered and portable equipment.
