Description
General part information
TPS7A5401 Series
The TPS7A54 is a low-noise (4.4 µVRMS), low-dropout linear regulator (LDO) capable of sourcing 4 A with only 175 mV of maximum dropout. The device output voltage is adjustable from 0.8 V to 5.1 V using an external resistor divider.
The combination of low noise (4.4 µVRMS), high PSRR, and high output current capability makes the TPS7A54 an excellent choice to power noise-sensitive components such as those found in radar power and infotainment applications. The high performance of this device limits power-supply-generated phase noise and clock jitter, making this device ideal for powering RF amplifiers, radar sensors, and chipsets. Specifically, RF amplifiers benefit from the high performance and 5.0-V output capability of the device.
For digital loads [such as application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), and digital signal processors (DSPs)] requiring low-input voltage, low-output (LILO) voltage operation, the exceptional accuracy (0.5% over load and temperature), remote sensing, excellent transient performance, and soft-start capabilities of the TPS7A54 provides optimal system performance.
