概述

Description

The TLE2426CDR is a versatile voltage regulator designed by Texas Instruments. Uniquely, it functions as a "Virtual Ground" device or rail splitter, making it ideal for applications requiring a precise dual power supply from a single voltage source. This is particularly useful in single-supply operational amplifier circuits where a midpoint voltage reference is needed.
Operating with an input voltage range from 4 V to 40 V, the TLE2426CDR can provide a stable output with a low dropout voltage, ensuring efficient performance. It is capable of sourcing small currents, typically up to 20 mA, which is sufficient for biasing requirements in many analog applications.
The device features a low quiescent current of around 60 µA and includes overload protection mechanisms such as thermal shutdown and current limiting, enhancing its reliability in various operating conditions. Packaged in a small form factor, it is suitable for compact designs.
Overall, the TLE2426CDR is ideal for applications in audio, portable equipment, and other systems needing split supply voltages with minimal components.
