... MCP1790/MCP1791 4.0 DEVICE OVERVIEW The MCP1790/MCP1791 are high input voltage regula- tors capable of providing current at output voltages up to 5.0V. The devices have an input voltage operating range from 6.0V to 30V, 48V absolute max. The MCP1790 devices are 3-pin devices consist- ing and GND. The MCP1791 devices ...

... Shutdown (SHDN) The MCP1791 has a Shutdown (SHDN) input signal that enables or disables the regulator output voltage. When the SHDN input signal is greater than 2.40V, the regulator output voltage is enabled. Note that the regulator output may still be disabled by the undervolt- age lockout incorporated within the V ...
Page 16
... Output Current and Current Limiting The MCP1790/MCP1791 devices are tested and ensured to supply a minimum output current. The MCP1790/MCP1791 also incorporate an output current limit foldback. When the regulator overcurrent condition, V will decrease with increas- OUT ing load. When V falls below 30% (typical OUT the output current will start to fold back ...
Page 17
... Power Good Output (PWRGD) The MCP1791 has an open-drain Power Good (PWRGD) output signal capable of sinking a minimum of 5 current while maintaining a PWRGD output voltage of 0.4V or less. As the output voltage of the LDO rises, the PWRGD output will be held low until the output voltage has ...
