LMT84-7 Eval Board layout

Other Parts Discussed in Thread: LMT87, LMT86, LMT85


I have 2 questions regarding the PCB layout of the LMT84-7 Eval Board:

  1. Why is there a zero-ohm resistor between the VDD pin 5 and other VDD pins for LMT85, LMT86 and LMT87 devices ?
  2. What is the use of the C5 capacitor ? Are bypass capacitors C2, C4, C7 and C9 not sufficient ?

Many thanks and best regards,
