| AME, Inc. AME8805 / 8810 600mA CMOS LDO n General Description The AME8805/8810 family of positive, linear regulators feature low quiescent current (30A typ.) with low dropout voltage, making them ideal for battery applications. The space-saving SOT-89 and SOT-223 packages are attractive for "Pocket" and "Hand Held" applications. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the "Worst" of operating conditions. The AME8805/8810 is stable with an output capacitance of 2.2F or greater. n Functional Block Diagram IN OUT Overcurrent Shutdown Thermal Shutdown R1 AMP Vref=1.215V R2 GND n Features l l l l l l l Very Low Dropout Voltage Guaranteed 600mA Output Accurate to within 1.5% 30A Quiescent Current Over-Temperature Shutdown Current Limiting Short Circuit Current Fold-back n Typical Application l Space-Saving SOT-89, SOT-223 l Factory Pre-set Output Voltages l Low Temperature Coefficient IN IN AME8805 OUT AME8810 GND OUT C1 5V 1F C2 2.2F n Applications l Instrumentation l Portable Electronics l l l l l Wireless Devices Cordless Phones PC Peripherals Battery Powered Widgets Electronic Scales 1 AME, Inc.

AME8805 / 8810 600mA CMOS LDO n Detailed Description The AME8805/8810 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 600mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120oC. The AME8805/8810 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. The AME8805/8810 also incorporates current foldback to reduce power dissipation when the output is short circuited. This feature becomes active 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 External Capacitors The AME8805/8810 is stable with an output capacitor to ground of 2.2F or greater. 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. Unfortunately, large value ceramic capacitors are comparatively expensive. One option is to parallel a 0.1F ceramic capacitor with a 10F Aluminum Electrolytic. The benefit is low ESR, high capacitance, and low overall cost. A second capacitor is recommended between the input and ground to stabilize Vin. The input capacitor should be at least 0.1F 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. 8 AME, Inc.
