Product No: WEA3615LD45GDownload Datasheet

  • Applications:
  • Maturity:silicon proven
  • Foundry:GF
  • Geometry (nm):45nm
  • Process Node:45RFSOI

The WEA3615LD45G is a voltage feedback amplifier (series – shunt) which active part is comprised of a telescopic cascode amplifier stage, followed by a PMOS pass – device which operates in saturation as a common source stage. The Current Limit Protection circuit detects an output current bigger than the prescribed value and the Power Good circuit detects when the output voltage of the LDO is within a certain range, in which the output is considered valid. Results validate a 1.5V output voltage from a 2.8 V to 3.6 V input voltage with a current dissipation of 3uA.
