TL391LVDBVR TI Low-Voltage Comparator | SOT-23-5 | 2.7V-5.5V, Open-Drain Output

Product Overview

The TL391LVDBVR is a low-voltage, low-power comparator from Texas Instruments, housed in a compact SOT-23-5 package. It operates from a single supply voltage range of 2.7V to 5.5V, making it ideal for battery-powered and portable applications. The device features an open-drain output that can be pulled up to any voltage up to 5.5V, independent of the supply voltage. With a typical propagation delay of 1.3 µs and a low supply current of 150 µA, the TL391LVDBVR offers excellent performance for general-purpose comparator applications.
