Présentation

Description

The TLE2426CDR is a versatile, precision voltage regulator from Texas Instruments, often used in low-dropout (LDO) applications. It functions as a "rail splitter," capable of splitting a single voltage rail into dual rails, which is particularly useful in creating virtual ground references for single-supply systems. This device can provide both positive and negative output voltages from a single input.
Key features of the TLE2426CDR include low quiescent current, high accuracy, and thermal shutdown protection. It operates over a wide input voltage range and offers a fixed output voltage, typically providing excellent line and load regulation. The device is packaged in a small, surface-mount form factor, making it suitable for compact applications.
Engineers often use the TLE2426CDR in battery-powered devices, audio equipment, and precision analog circuits due to its reliable performance and straightforward implementation. Its ability to work without additional external components simplifies circuit design and enhances stability in various applications.
