Linear Regulator to supply digital islands in TSMC 40nm uLP-eFlash

Key Benefits

  • Low dropout: 380mV of dropout at ILOAD= IMAX
  • Low Bill-of-Material: optimized in density for the best trade-off for the given output current and input voltage range
  • A cost-efficient solution compared to external Power Management
  • Behavioral models: ease of integration in SoC and optimization of Power Management Network (PMNet) using models to verify mode transitions as well as noise propagation
  • Safe integration in the SoC thanks to transfer functions, templates and profiles included in the specification
