TPS74401KTWT  

Linear & Switching Voltage Regulators

TPS74401KTWT Description

The TPS74401KTWT from Texas Instruments is a high-performance, adjustable linear voltage regulator designed to deliver up to 3A of output current with an input voltage range up to 5.5V. This positive-output regulator offers an adjustable output voltage from 0.8V to 3.6V, making it versatile for a wide range of low-voltage applications. The device features a low dropout voltage of 0.24V at 3A, ensuring efficient operation even with tight input-output differentials. Packaged in a surface-mount DDPAK and supplied in Tape & Reel (TR), it is suitable for automated assembly processes.

TPS74401KTWT Features

• High Efficiency: Low dropout voltage minimizes power dissipation, ideal for power-sensitive designs.
• Advanced Control & Protection: Includes Enable, Power Good, and Soft Start functions, along with comprehensive protection against overcurrent, overtemperature, short-circuit, and UVLO.
• Excellent Noise Performance: PSRR of 73dB to 50dB (1kHz–800kHz) ensures clean output in noise-sensitive applications.
• Robust Design: ROHS3 compliant and REACH unaffected, meeting stringent environmental standards.
• Thermal Management: Moisture Sensitivity Level (MSL) 3 rating ensures reliability in humid conditions.

TPS74401KTWT Applications

• FPGA/ASIC Power Supplies: Provides stable, low-noise power for high-performance processors.
• Industrial Automation: Suitable for PLCs, motor drives, and control systems requiring precise voltage regulation.
• Telecom Infrastructure: Ideal for base stations and networking equipment due to its high current capability and protection features.
• Portable Electronics: Efficient power management for battery-operated devices with tight voltage margins.

Conclusion of TPS74401KTWT

The TPS74401KTWT stands out as a high-current, adjustable linear regulator with superior noise rejection and robust protection features. While marked as obsolete, its performance in low-dropout, high-PSRR applications remains unmatched for legacy designs. Engineers seeking reliable power management for industrial, telecom, or embedded systems will find this regulator a compelling choice, despite its discontinued status. For new designs, consider Texas Instruments' newer alternatives within the TPS744 series or equivalent offerings.
