Dear all,
If I choose capacitor like ceramic capacitor or Tantalum capacitor, which is
cheaper? My bulk is voltage mode, which compensation is suit for lower esr (like
30 mohm). Generally, the esr of ti or analog device's bulk is used from ? to ?.
Can bulk be used the small esr? Is phase margin bigger than 30 or 40 ? thanks.
