As an alternative, a resistor can be connected between GND and V
this resistor must be sized such that the maximum load current does not exceed
500 mA for the selected output voltage.
Note:
Figure 2-2. In this configuration the output voltage will appear between the V
terminal and GND terminal of the board.
The MCP1603 device will be able to provide full load current in this configuration.
