Possible causes and recommended corrective actions are as follows. Cause: The output oscillates. Action: Verify the connection of the capacitor between the input and output. Cause: The current flowing exceeds the peak output current. Action: Lower the input voltage, which effectively decreases heat and, as a result, the chip temperature. *Please note that a relatively high current is necessary in order to start up the regulator when a motor or lamp is connected as the load. Cause: The chip temperature exceeds 150ºC. Action: Lower the chip temperature, which effectively decreases heat and, as a result, the chip temperature. Cause: The input and output are connected in reverse. Action: Check the pin connections.
