9 During normal operation, the error ampli-fier compares the output voltage to a precision and Thermal shutdown circuits become ac-tive when the junction temperature exceeds 140oC, orthe current exceeds During thermal shutdown, theoutput voltage remains low. Normal operation is restoredwhen the junction temperature drops below AME8816 behaves like a current source when theload reaches However, if the load impedance dropsbelow ohms, the current drops back to 600mA toprevent excessive power dissipation.

10 Normal operationis restored when the load resistance exceeds Detailed Descriptionn External CapacitorsThe AME8816 is stable with an output capacitor toground of or greater. Ceramic capacitors have thelowest ESR, and will offer the best AC performance. Con-versely, Aluminum Electrolytic capacitors exhibit the high-est ESR, resulting in the poorest AC response. Unfortu-nately, large value ceramic capacitors are comparativelyexpensive. One option is to parallel a ceramiccapacitor with a 10mF Aluminum Electrolytic.
