Texas Instruments  TPS7A5401QRGRRQ1

The TPS7A54-Q1 deviceis a low-noise (4.4 µVRMS), low-dropout linear regulator (LDO) capable ofsourcing 4 A with only 240 mV of maximum dropout. The device output voltage isadjustable from 0.8 V to 5.1 V using an external resistor divider.

The combination of low-noise (4.4 µVRMS), high-PSRR, and highoutput current capability makes the TPS7A54-Q1 ideal to power noise-sensitive components such as those found inradar power and infotainment applications. The high performance of this device limitspower-supply-generated phase noise and clock jitter, making this device ideal for powering RFamplifiers, radar sensors, and chipsets. Specifically, RF amplifiers benefit from thehigh-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-inputvoltage, low-output (LILO) voltage operation, the exceptional accuracy (1% over load andtemperature), remote sensing, excellent transient performance, and soft-start capabilities of theTPS7A54-Q1 provides optimalsystem performance.

The versatility of the TPS7A54-Q1 makes the device a component of choice for many demandingapplications.
