TPS7A5401QRGRRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS7A5401QRGRRQ1 is an automotive-grade, 4-ampere low-dropout (LDO) linear voltage regulator. It features a low input voltage capability starting at 1.1V and an adjustable output voltage range from 0.8V to 5.1V. This device is engineered for low noise and high accuracy, making it suitable for sensitive power supply applications.

 

Key electrical characteristics include a maximum output current of 4A, a typical dropout voltage of 0.51V at 4A, and a quiescent current of 3mA. The regulator provides a PSRR of 42dB to 25dB across a frequency range of 10kHz to 500kHz, helping to suppress power supply noise. It operates within a wide temperature range of -40°C to 150°C (TJ).

 

The TPS7A5401QRGRRQ1 is available in a 20-VQFN Exposed Pad package, measuring 3.5mm x 3.5mm, and is designed for surface mounting. Protection features include over-temperature and reverse polarity protection. The device is also noted as being Functional Safety-Capable and AEC-Q100 qualified, indicating its suitability for demanding automotive environments.
