Hot-selling and scarce TPS7A8500RGRT 4A 1% 4.4µV RMS LDO Voltage Regulator 20-VQFN spot stock

Product Descriptions

The TPS7A85 is a low-noise (4 .4 µV_RMS), low-dropoutlinear regulator (LDO) capable of sourcing 4 A withonly 240 mV of maximum dropout . The device outputvoltage is pin-programmable from 0.8 V to 3.95 V andadjustable from 0.8 V to 5.0 V using an externalresistor divider .

The combination of  low-noise (4 .4 µV_RMS),  highPSRR, and high output current capability makes theTPS7A85 ideal to power noise-sensitive componentssuch as those found in high-speed communications,video,     medical,     or    test     and  measurementapplications . The high performance of the TPS7A85limits power-supply-generated phase noise and clockjitter,  making this device ideal  for  powering highperformance serializer  and deserializer  (SerDes),analog-to-digital  converters (ADCs), digital-to-analogconverters (DACs), and RF components . Specifically,RF amplifiers benefit from the high-performance and5. 0-V output capability of the device .

For   digital     loads  [such  as  application-specificintegrated circuits (ASICs), field-programmable gatearrays  (FPGAs),   and digital    signal     processors(DSPs)] requiring low-input voltage, low-output (LILO)voltage operation,  the exceptional  accuracy (0 . 75%over   load  and  temperature),    remote  sensing,excellent    transient    performance,    and  soft-startcapabilities of the TPS7A85 ensure optimal  systemperformance .
