FIGURE 7-1:
When doing the physical layout for the TC1301A/B, the
highest priority is placing the input and output
capacitors as close to the device pins as is practical.
Figure 7-1 above represents a typical placement of the
components when using SMT0805 capacitors.
FIGURE 7-2:
A wiring example for the TC1301A is shown. The vias
represent the connection to a ground plane that is
below the wiring layer.
