| AME, Inc. AME8822 n General Description The AME8822 family of positive, linear regulators feature low quiescent current (30A typ.) low dropout voltage and excellent PSRR, thus making them ideal for telecommunications and other battery applications. These rugged devices have both thermal shutdown and current limit to prevent device failure under the "Worst" operating conditions. The AME8822 is stable with an output capacitance of 1F or larger.

Rev.D.05 9 AME, Inc. AME8822 n Detailed Description 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 protection circuits. During normal operation, the error amplifier compares the output voltage to a precision reference. Over-current and thermal shutdown circuits become active when the junction temperature exceeds 150oC, or the current exceeds 250mA. During thermal shutdown, the output voltage remains low. Normal operation is restored 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. High PSRR, 250mA CMOS LDO 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 1A. This pin can' t be floating. n External Capacitors The AME8822 is stable with an output capacitor to ground of 1F or larger. Ceramic capacitors have the lowest ESR, and will offer the best AC performance. Conversely, Aluminum Electrolytic capacitors exhibit the highest ESR, resulting in the poorest AC response. A second capacitor is recommended between the in- p ta dg o n t s a i i eV. The input capacitor should u n r u d o t b l z IN be at least 1F to have a beneficial effect. 10 Rev.D.05 AME, Inc.
