UC385TDKTTT-3 TI LDO Regulator | TO-263 (DDPAK-5) | 3.3V Output, 5A Current

Product Overview

The UC385TDKTTT-3 from Texas Instruments is a high-performance, low-dropout (LDO) voltage regulator designed to deliver a fixed 3.3V output with a maximum current of 5A. 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 340mV at full load, it ensures efficient operation even when the input voltage is close to the output. The UC385TDKTTT-3 features fast transient response, low output noise, and built-in protection circuits including overcurrent and thermal shutdown.
