10 / 18 page AME, Inc. 10 High PSRR, 250mA CMOS LDO AME8822 Rev.D.05 The AME8822 is stable with an output capacitor to ground of 1 µF or larger. Ceramic capacitors have the low- est ESR, and will offer the best AC performance. Con- versely, Aluminum Electrolytic capacitors exhibit the high- est ESR, resulting in the poorest AC response. A second capacitor is recommended between the in- putandgroundtostabilizeV IN. The input capacitor should be at least 1 µF to have a beneficial effect. n Detailed Description n External Capacitors n Enable The Enable Pin is normally pull-high. When activated pulled low, the PMOS pass transistor shuts off, and all internal circuits are powered down. In this state, the stand by current is less than 1 µA. This pin can’t be floating. The AME8822 family of CMOS regulators contain 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 150oC, or the current exceeds 250mA. During thermal shutdown, the output voltage remains low. Normal operation is re- stored when the junction temperature drops below 130oC. The AME8822 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. |
