TPS77450DGK TI LDO Regulator | 8-VSSOP | 5V Output, 750mA

Product Overview

The TPS77450DGK from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed to deliver a fixed 5V output with a maximum output current of 750mA. Housed in a compact 8-VSSOP package, this device offers excellent line and load regulation, making it suitable for noise-sensitive applications. With a dropout voltage of typically 300mV at full load, it ensures efficient operation even when the input voltage is close to the output. The TPS77450DGK integrates overcurrent and overtemperature protection, enhancing system reliability.
