The MCP1790/MCP1791 devices are tested and
ensured to supply a minimum of 70 mA of output
current.
The MCP1790/MCP1791 also incorporate an output
current limit foldback. When the regulator is in an
overcurrent condition, V

the output current will start to fold back. The output
current will fold back to less than 100 mA (typical) when
