Figure 6. Example application, Vout=1.2V.
Figure 7 shows an example schematic using an external voltage divider. VS0=VS1=VS2= “1”. The
resistor values are chosen to give an output voltage of 2.6V.
Figure 7. Schematic showing the use of external divider option, Vout = 2.6V.
Figure 8 shows two example board layouts. Note the placement of the input and output capacitors.
They are placed close to the device to minimize the physical area of the AC current loops. Note the
placement of the vias per recommendation 3.
