TPS2055AD TI Power Distribution | 8-SOIC | 0.5A, 2.7-5.5V

Product Overview

The TPS2055AD from Texas Instruments is a high-side power-distribution switch designed for applications requiring up to 0.5A 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 integrates a 70mΩ N-channel MOSFET, active-high enable, and built-in protection features including overcurrent, thermal shutdown, and reverse current blocking. Housed in an 8-pin SOIC package, it offers a compact solution for power management in space-constrained designs.
