ame 7 ame8810 600ma cmos ldo rev.a.05 the ame8810 of cmos regulators contains a pmos pass transistor, voltage reference, error amplifier, over- current protection, and thermal shutdown. the p-channel pass transistor receives data from the error amplifier, over-current shutdown, and thermal pro- tection circuits. during normal operation, the error ampli- fier compares the output voltage to a precision reference. over-current and thermal shutdown circuits become ac- tive when the junction temperature exceeds 150 o c, or the current exceeds 600ma. during thermal shutdown, the output voltage remains low. normal operation is re- stored when the junction temperature drops below 120 o c. the ame8810 switches from voltage mode to current mode when the load exceeds the rated output current. this prevents over-stress. the ame8810 also incorpo- rates current foldback to reduce power dissipation when the output is short circuited. this feature becomes ac- tive when the output drops below 0.8 volts, and reduces the current flow by 65%. full current is restored when the voltage exceeds 0.8 volts. n detailed description n external capacitors the ame8810 is stable with an output capacitor to ground of 2.2 m f or greater. ceramic capacitors have the lowest 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 comparatively expensive. one option is to parallel a 0.1 m f ceramic ca- pacitor with a 10 m f aluminum electrolytic. the benefit is low esr, high capacitance, and low overall cost. a second capacitor is recommended between the in- put and ground to stabilize vin. the input capacitor should be at least 0.1 m f to have a beneficial effect. all capacitors should be placed in close proximity to the pins. a "quiet" ground termination is desirable. this can be achieved with a "star" connection.
