Texas Instruments PTPS7A5301RPSR
The TPS7A53 is a low-noise (4.4 µVRMS), low-dropout linearregulator (LDO) capable of sourcing 3 A with only 180 mV of maximum dropout. Thedevice output voltage is adjustable from 0.8 V to 5.2 V using an external resistor divider.
The combination of low-noise (4.4 µVRMS), high PSRR, and highoutput current capability makes the TPS7A53 an excellent choice to power noise-sensitive componentssuch as those found in high-speed communications, video, medical, or test-and-measurementapplications. The high performance of this device limits power-supply-generated phase noise andclock jitter, making this device ideal for powering high-performance serializer and deserializer(SerDes), analog-to-digital converters (ADCs), and digital-to-analog converters (DACs).Specifically, RF amplifiers benefit from the high performance and 5.2-V output capability of thedevice.
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 (0.75% over load andtemperature), remote sensing, excellent transient performance, and soft-start capabilities of theTPS7A53 provides optimal system performance.
As an adjustable voltage regulator, there is versatility in the design of the TPS7A53that makes the device a component of choice for analog loads such as VCO, ADC, DAC, and imagingsensors and for digital loads such as SerDes, FPGAs, and DSPs.
