Key Benefits

  • Starring a PSRR of -65 dB at 20 kHz and a low intrinsic noise, combined with a low quiescent current of 110 uA, the nLR-VAIPO helps optimize the power management network for audio handheld applications such as smartphone and tablet.
  • Small footprint: only 0.12 mm2 (including bandgap reference and POK circuit)
  • Minimization of the overall system power, through the support of 3 modes of operation: normal, shutdown and bypass
  • Eases integration in SoC nLR-VAIPO is delivered with behavioral models. These new views enable to build an optimized Power Management Network (PMNet) by verifying mode transitions as well as noise propagation.
