Capacitor-less low input voltage LDO in GlobalFoundries 22FDX with programmable output voltage to supply core logic domain, SRAM array or RF/analog domain. It features normal and low-power (LP) operating modes to adjust the amount of output current depending on the application requirements.

Key Benefits

  • Low silicon area
  • Fast transient
  • Low BoM cost, no output capacitor required
  • Low-power (LP) mode to supply AON domain with low quiescent current
