TPS75518KTTR TI LDO Regulator | TO-263 (DDPAK-5) | 5A, 1.8V Output

Product Overview

The TPS75518KTTR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver up to 5A of continuous output current with a fixed output voltage of 1.8V. Housed in a TO-263 (DDPAK-5) package, this device offers excellent thermal performance and reliability for demanding applications. With a low dropout voltage of typically 300mV at full load, it ensures efficient regulation even when the input voltage is close to the output. The TPS75518KTTR integrates advanced protection features including overcurrent limiting, over-temperature shutdown, and reverse battery protection, making it a robust solution for power management in industrial, automotive, and telecommunications systems.
