EVALUATION BOARD HARDWARE

POWER MANAGEMENT OF THE OUTPUT (LDO)

The ADP5091 has an additional regulated output containing an
LDO and a boost. On this evaluation board, the boost is always
shut down. With the options of different resistor values, the
LDO can generate different output voltages. Table 1 shows the
jumper connections and the corresponding output voltage on
the ADP5091-2-EVALZ. See the Evaluation Board Schematic
section for more details.
