TPS74401RGWR TI LDO Regulator | 20-VQFN (5x5) | 3A, 0.8-3.6V Output

Product Overview

The TPS74401RGWR 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 0.8V to 3.6V, making it suitable for powering low-voltage core supplies in modern digital systems. The device is housed in a compact 20-pin VQFN package (5mm x 5mm) with excellent thermal performance. With a low dropout voltage of typically 115mV at 3A, the TPS74401RGWR ensures high efficiency even under heavy loads. It also offers high accuracy (±1% over line, load, and temperature), fast transient response, and low output noise, making it ideal for noise-sensitive applications such as RF, analog, and high-speed digital circuits.
