11 Layout

11.1 Layout Guidelines

  • For the first supply input (IN1), place the 0.1-μF bypass capacitor between the IN1 and GND as close as possible ensuring a low-impedance trace.
  • For the second supply input (IN2), place the 0.1-μF bypass capacitor between the IN2 and GND as close as possible ensuring a low-impedance trace.
  • Place a high-value capacitor and a 0.1-μF bypass capacitor between OUT and GND. The recommendation is to use the high-value capacitor when expecting large-load transients on the output. This trace should be low-impedance to the load.
  • Place the resistor used to set the current limit between ILIM and GND. Make sure the traces routing the RILIM resistor to the device are as short as possible to reduce parasitic effects on the current limit accuracy.
