TPS74401KTWRG3 Description

Short technical summary and product information.

The Texas Instruments TPS74401KTWRG3 is a high-performance, 3A adjustable ultra-low-dropout (LDO) linear voltage regulator designed for various power management applications. It supports an input voltage range from 0.8V to 5.5V and offers an adjustable output voltage from 0.8V to 3.6V.

 

Key electrical characteristics include a low noise output of 20 µVrms and high PSRR of up to 50 dB at 100 KHz. The device provides a typical dropout voltage of 120mV at 3A, ensuring efficient operation. It features integrated protection functions such as over current, over temperature, and short circuit protection, along with under voltage lockout (UVLO).

 

This regulator is available in a surface mount DDPAK/TO-263-7 package, suitable for space-constrained designs. The operating temperature range is -40°C to 125°C, making it robust for demanding environments. Control features include Enable, Power Good, and programmable Soft Start for in-rush current control.
