LP87524B-Q1: LP87524B-Q1 datasheet

Part Number: LP87524B-Q1
Other Parts Discussed in Thread: AWR1642


For the mmwave radar sensor hardware design, using PMIC LP87524B-Q1, its datasheet recommends connecting an input filter capacitor (10 uF) from VIN_Bx to PGND_Bx. However, the design files included in Short Range Radar Reference Design Using AWR1642 Schematic and Block Diagram doen't have this input filter (instead the 5V_UNREG is connected directly to the 4 VIN_Bx pins). Is the input filter cap necessary?
