TPS78618KTTR TI LDO Regulator | TO-263 (DDPAK-5) | 1.8V Output, 1.5A

Product Overview

The TPS78618KTTR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver a fixed 1.8V output with a maximum output current of 1.5A. Housed in a TO-263 (DDPAK-5) package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. With a dropout voltage as low as 300mV at full load, the TPS78618KTTR ensures efficient operation even when the input voltage is close to the output. Its low quiescent current and fast transient response further enhance its suitability for powering sensitive analog and digital circuits.
