The TPS7A85A is a low-noise (4.4 µVRMS), low dropout linearregulator (LDO) capable of sourcing 4 A with only 240 mV of maximum dropout. The device outputvoltage is pin-programmable from 0.8 V to 3.95 V and adjustable from 0.8 V to 5.1 V using anexternal resistor divider.
The combination of low-noise (4.4 µVRMS), high- PSRR, and highoutput current capability makes the TPS7A85A ideal to power noise-sensitive components such asthose found in high-speed communications, video, medical, or test and measurement applications. Thehigh performance of the TPS7A85A limits power-supply-generated phase noise and clock jitter, makingthis device ideal for powering high-performance serializer and deserializer (SerDes),analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and RF components.Specifically, RF amplifiers benefit from the high-performance and 5.1-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 theTPS7A85A ensure optimal system performance.
The versatility of the TPS7A8500A makes the device a component of choice for manydemanding applications.
