Explanation: The IC regulator has a temperature sensor (built-in) which turn off the IC, when it becomes too hot (usually 125oC-150oC). The output current will drop and remains there until the IC has cooled significantly. 7. Find the difference between output current having a load of 100Ω and 120Ω for 7805 IC regulator. Consider the following specification: Voltage across the load = 5v; Voltage across the internal resistor= 350mv.
