MCP1790/MCP1791
4.8 Output Current and Current
Limiting
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 OUT will decrease with
increasing load. When V OUT falls below 30% (typical)
of V R , the output current will start to fold back. The
output current will fold back to less than 100 mA
The 5.0V regulator has an overload current limiting of
approximately 120 mA. If V REG is lower than 3.5V, I OUT
will start to fold back and decrease along with V REG
until I OUT is less than 105 mA and V REG is near 0 volts.
The 3.3V regulator has an overload current limiting of
approximately 130 mA. If V REG is lower than 2.5V, I OUT
will start to fold back and decrease along with V REG
until I OUT is less than 99 mA and V REG is near 0 volts.
(typical) when V OUT is near 0 volts.
