TPS75801KTTRG3 TI LDO Regulator | TO-263 (DDPAK-5) | 3A, Adjustable Output

Product Overview

The TPS75801KTTRG3 from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator capable of delivering up to 3A of output current. It features an adjustable output voltage range from 1.22V to 5.5V, making it suitable for a wide variety of applications. The device is housed in a TO-263 (DDPAK-5) package, which offers excellent thermal performance for high-power designs. With a low dropout voltage of typically 350mV at 3A, the TPS75801KTTRG3 ensures efficient regulation even when the input voltage is close to the output voltage. It also includes built-in protection features such as overcurrent and overtemperature shutdown, enhancing system reliability.
