TPS2051D TI Power Switch | 8-SOIC | 0.5A, 2.7-5.5V

Product Overview

The TPS2051D from Texas Instruments is a single-channel, current-limited power-distribution switch designed for applications where heavy capacitive loads and short circuits are likely. It operates over an input voltage range of 2.7V to 5.5V and provides a continuous output current of up to 0.5A. The device features a 70mΩ N-channel MOSFET switch and includes thermal shutdown protection. The TPS2051D is available in an 8-pin SOIC package, making it suitable for space-constrained designs.
