... For some applications, there are pulsed load current events that may exceed the specified 150 mA maximum specification of the MCP1804. The internal current limit of the MCP1804 will prevent high peak load demands from causing non-recoverable damage. The 150 mA rating is a maximum average continuous rating ...
