TPS2551DBVT TI Power Switch | SOT-23-6 | 0.5A-2.5A, Adjustable Current Limit

Product Overview

The TPS2551DBVT from Texas Instruments is a precision adjustable current-limited power-distribution switch designed for applications where heavy capacitive loads and short circuits are encountered. This device offers a programmable current-limit threshold between 0.5 A and 2.5 A via an external resistor. It operates over a wide input voltage range of 2.5 V to 6.5 V, making it suitable for 3.3 V and 5 V power rails. The TPS2551DBVT is housed in a compact SOT-23-6 package, ideal for space-constrained designs.
