TPS78633KTTT TI LDO Regulator | TO-263 (DDPAK-5) | 3.3V Output, 1.5A

Product Overview

The TPS78633KTTT from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver a fixed 3.3V output with a maximum current of 1.5A. Housed in a TO-263 (DDPAK-5) package, this device offers excellent line and load regulation, low dropout voltage, and low quiescent current, making it ideal for power-sensitive applications. The TPS78633KTTT features a wide input voltage range from 2.7V to 5.5V, enabling operation from standard 3.3V and 5V rails. Its fast transient response and low output noise ensure stable power delivery to noise-sensitive loads such as analog circuits, RF modules, and high-speed digital processors.
