SBVS311A November 2019 – March 2020 TPS7A54
The TPS7A54 is a high-current (4 A), low-noise (4.4 µVRMS), high accuracy (1%) low-dropout linear voltage regulator with an input range of 1.1 V to 6.5 V and an output voltage range of 0.8 V to 5.1 V. The TPS7A54 has an integrated charge pump for ease of use, and an external bias rail to allow for the lowest dropout across the entire output voltage range. Table 1 categorizes the functions shown in the Functional Block Diagram. These features make the TPS7A54 a robust solution to solve many challenging problems by generating a clean, accurate power supply in a variety of applications.
