TPS2105D TI Power Distribution Switch | 8-SOIC | 0.5A, 2.7V-5.5V

Product Overview

The TPS2105D from Texas Instruments is a high-side power distribution switch designed for applications requiring precise current limiting and thermal protection. Housed in an 8-SOIC package, this device provides a single-channel output with a continuous current rating of 0.5A. It operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for various low-voltage systems. The TPS2105D integrates an N-channel MOSFET with low on-resistance (typically 70mΩ) to minimize power dissipation. It features active-high enable logic, built-in overcurrent protection, and thermal shutdown to ensure safe operation under fault conditions.
