TPS2081D TI Power Distribution | 8-SOIC | 0.5A, 2.7-5.5V

Product Overview

The TPS2081D from Texas Instruments is a single-channel, current-limited power-distribution switch designed for applications requiring up to 0.5A of continuous current. It operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for both 3.3V and 5V systems. The device features a low on-resistance (70mΩ typical) N-channel MOSFET switch, ensuring minimal voltage drop and power dissipation. It includes over-current, over-temperature, and reverse-current protection, enhancing system reliability. The TPS2081D is available in an 8-pin SOIC package, ideal for space-constrained designs.
