| Analog Microelectronics, Inc. AME8806 / 8809 / 8842 600mA CMOS LDO n General Description The AME8806/8809 family of positive, linear regulators feature low quiescent current (30A typ.) with low dropout voltage, making them ideal for battery applications. The space-saving SO-8 package is 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. In applications requiring a low noise, regulated supply, place a 1000 pF capacitor between Bypass and ground. The AME8806/8809 is stable with an output capacitance of 2.2F or greater. n Features l l l l l 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 Noise Reduction Bypass Capacitor Power-Saving Shutdown Mode Space-Saving SO-8 Package Factory Pre-set Output Voltages Low Temperature Coefficient n Applications l l n Functional Block Diagram IN Overcurrent Shutdown l l l l l OUT Instrumentation Portable Electronics Wireless Devices Cordless Phones PC Peripherals Battery Powered Widgets Electronic Scales Thermal Shutdown n Typical Application IN IN OUT OUT EN BYP AMP 5V AME8806 AME8809 GND EN R1 C1 1F BYP C2 1F C3 2.2 F V ref=1.215V R2 GND 1 Analog Microelectronics, Inc.

AME8806 / 8809 / 8842 600mA CMOS LDO n Detailed Description The AME8806/8809 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 AME8806/8809 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. The AME8806/8809 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. A third capacitor can be connected between the BYPASS pin and GND. This capacitor can be a low cost Polyester Film variety between the value of 0.001 ~ 0.01F. A larger capacitor improves the AC ripple rejection, but also makes the output come up slowly. This "Soft" turn-on is desirable in some applications to limit turn-on surges. 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. n Enable The Enable pin normally floats high. When actively, pulled low, the PMOS pass transistor shuts off, and all internal circuits are powered down. In this state, the quiescent current is less than 1A. This pin behaves much like an electronic switch. n External Capacitors The AME8806/8809 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. 8 Analog Microelectronics, Inc.
