11.1 Layout Guidelines
The decoupling capacitor for the power supply (V_DD should be placed close to the device pin. The filtering
capacitor for the regulator (REG) should be placed close to the device REG pin. When creating the pad size for
the WCSP pins, TI recommends that the PCB layout use nonsolder mask-defined (NSMD) land. With this
method, the solder mask opening is made larger than the desired land area and the opening size is defined by
the copper pad width.
