TPS74401RGWR Description

Short technical summary and product information.

The TPS74401RGWR from Texas Instruments is a high-performance linear voltage regulator designed for demanding applications. It delivers up to 3A of output current with an adjustable output voltage ranging from 0.8V to 3.6V.

Key electrical characteristics include an ultra-low dropout voltage of 120mV at 3A, low noise operation with 20 µVrms, and high power supply rejection ratio (PSRR) of 50 dB at 100 KHz. The regulator operates over a wide input voltage range of 0.8V to 5.5V and features accuracy of 1% over line, load, and temperature.

Designed for ease of use, the TPS74401RGWR includes features such as Enable, Power Good, and programmable Soft Start for controlled power-up sequences. It is stable with a minimum output capacitance of 2.2 µF.

This device is available in a 20-VQFN (5x5 mm) surface-mount package, suitable for space-constrained designs. The operating temperature range is -40°C to 125°C.
