TPS74401KTWT Description

Short technical summary and product information.

The Texas Instruments TPS74401KTWT is an ultra-low dropout (LDO) linear regulator designed for robust power management solutions. It offers an adjustable output voltage ranging from 0.8 V to 3.6 V and can supply up to 3 A of current.

 

Key electrical specifications include an input voltage range of 1.1 V to 5.5 V and an ultra-low dropout voltage of 115 mV at 3.0 A. The device provides 1% accuracy over line, load, and temperature variations. It supports advanced control features such as an enable pin, power-good output, and a user-programmable soft-start pin, which minimizes input power source stress by reducing inrush current during startup.

 

The TPS74401KTWT operates within a temperature range of -40°C to 125°C. It is available in a DDPAK/TO-263-7 surface mount package, offering a compact solution for various applications.

 

This LDO is well-suited for applications requiring specific start-up time or sequencing, such as FPGA core and I/O voltages, DSP core and I/O voltages, and post-regulation applications. Its stability with any or no output capacitor and excellent transient response make it a versatile choice for demanding designs.
