10.1 Layout Guidelines

The LP5524 high-side current source outputs provide a fast load transient (350 nsec typical) to the external load. Design the PCB to provide a low resistive/inductive path to the VIN and GND pins. If the optional input capacitor (CIN) is used, place it close to the LP5524 VIN and GND pins.
