LP3873ESX-3.3 TI LDO Regulator | DDPAK/TO-263-5 | 3A, 3.3V Output

Product Overview

The LP3873ESX-3.3 is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 3.3V output with a maximum current of 3A. Housed in a DDPAK/TO-263-5 package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. With a dropout voltage of only 240mV at 3A, it ensures efficient operation even under low input-to-output voltage differentials. The LP3873ESX-3.3 integrates protection features such as overcurrent and overtemperature shutdown, enhancing system reliability.
