TPS2103DBVT TI Power Distribution Switch | SOT-23-5 | 0.5A, 2.7-5.5V

Product Overview

The TPS2103DBVT from Texas Instruments is a high-side power-distribution switch designed for applications requiring precision current limiting and thermal protection. Housed in a compact SOT-23-5 package, this device integrates a 70mΩ N-channel MOSFET with a charge pump to provide efficient power switching. 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 TPS2103DBVT features an enable pin for ON/OFF control and a fault flag output that asserts during overcurrent or overtemperature conditions. With a continuous output current rating of 0.5A, it is ideal for powering USB peripherals, portable devices, and other low-power loads.
