TPS78405KTTR TI LDO Regulator | TO-263 (DDPAK-5) | 5V Output, 1A

Product Overview

The TPS78405KTTR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver a fixed 5V output with a maximum current of 1A. Housed in a robust TO-263 (DDPAK-5) package, this device offers excellent thermal performance and reliability for demanding applications. With a dropout voltage as low as 250mV at full load, it ensures efficient operation even under low input-to-output voltage differentials. The TPS78405KTTR integrates protection features such as overcurrent and overtemperature shutdown, making it a safe and reliable choice for power management in industrial, automotive, and telecommunications systems.
