EVALUATION BOARD HARDWARE
POWER MANAGEMENT OF THE OUTPUT (LDO)
A low dropout (
) is included on the demo board (the
evaluation board). This regulator chooses
different output voltages. Table 1 shows the jumper connections
and the corresponding output voltage on the
evaluation board. See the Evaluation Board Schematic
and Artwork section for more details. Set the output of the
demo board corresponding to each Table 1 setting as shown in
Figure 4 to Figure 8.
