6 ame8815 family of cmos regulators contain aPMOS pass transistor, voltage reference, error amplifier,over-current protection, and thermal P-channel pass transistor receives data from theerror amplifier, over-current shutdown, and thermal pro-tection circuits. 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 150oC, orthe current exceeds During thermal shutdown, theoutput voltage remains low. Normal operation is restoredwhen the junction temperature drops below ame8815 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.

7 Normal operationis restored when the load resistance exceeds Detailed Descriptionn External CapacitorsThe ame8815 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 ceramic ca-pacitor with a 10mF Aluminum Electrolytic. The benefit islow ESR, high capacitance, and low overall second capacitor is recommended between the in-put and ground to stabilize Vin. The input capacitor shouldbe at least to have a beneficial capacitors should be placed in close proximity tothe pins.
