10.1 Layout Guidelines

Bypass the VM terminal to GND using a low-ESR ceramic bypass capacitor with a recommended value of 10 µF rated for VM. This capacitor should be placed as close to the VM pin as possible with a thick trace or ground plane connection to the device GND pin and PowerPAD.

Bypass VINT to ground with a ceramic capacitor rated 6.3 V. Place this bypassing capacitor as close to the pin as possible.
