| AME, Inc. AME8815 1.5A CMOS LDO n General Description The AME8815 family of linear regulators feature low quiescent current (45A typ.) with low dropout voltage, making them ideal for battery applications. It is available in D2PAK and TO-220 packages. The space-efficient SOT-223 and DPAK package are attractive for "Pocket" and "Hand Held" applications. Output voltages are set at the factory and trimmed to 1.5% accuracy. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the "Worst" of operating conditions. The AME8815 is stable with an output capacitance of 4.7F or greater. n Features l l l l l l l l l Very Low Dropout Voltage Guaranteed 1.5A Output Accurate to within 1.5% 45A Quiescent Current Typically Over-Temperature Shutdown Current Limiting Short Circuit Current Fold-back Space-Efficient DPAK or SOT223 Package Low Temperature Coefficient n Applications l l l n Functional Block Diagram IN OUT l l Instrumentation Portable Electronics Wireless Devices PC Peripherals Battery Powered Widgets Overcurrent Shutdown Thermal Shutdown n Typical Application R1 IN IN AME8815 GND OUT OUT AMP C1 5V C2 1F 1.215V R2 GND 4.7 F 1 AME, Inc.

AME8815 1.5A CMOS LDO n Detailed Description The AME8815 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 2.2A. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120oC. The AME8815 behaves like a current source when the load reaches 2.2A. However, if the load impedance drops below 0.3 ohms, the current drops back to 600mA to prevent excessive power dissipation. Normal operation is restored when the load resistance exceeds 0.75 ohms. n External Capacitors The AME8815 is stable with an output capacitor to ground of 4.7F 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. 10 AME, Inc.
