AME AME8815 n General Description The AME8815 family of linear regulators feature low quiescent current (45µA typ.) with low dropout voltage, making them ideal for battery applications. It is available in TO-252, SOT-223, TO-263 and TO-220 packages. 1.5A CMOS LDO n Functional Block Diagram VOUT VIN Overcurrent Shutdown Thermal Shutdown Output voltages are set at the factory and trimmed to 1.5% accuracy. R1 These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the "Worst" operating conditions. AMP The AME8815 is stable with an output capacitance of 4.7µF or greater.

S.07 AME AME8815 1.5A CMOS LDO n Detailed Description n External Capacitors The AME8815 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current protection, and thermal shutdown. The AME8815 is stable with an output capacitor to ground of 4.7µF 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 0.1µF ceramic capacitor with a 10µF Aluminum Electrolytic. The benefit is low ESR, high capacitance, and low overall cost. 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. Rev. S.07 A second capacitor is recommended between the input and ground to stabilize Vin. The input capacitor should be at least 0.1µF 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. 19 AME AME8815 1.5A CMOS LDO Dropout Voltage vs. ILOAD Dropout Voltage vs. VOUT 1 1.2 VOUT=1.5 ILOAD=1.5A 0.8 Dropout Voltage (V) Dropout Voltage (V) 1 1.8 0.8 2.0 0.6 2.1 0.4 2.8 0.2 3.3 0 0 0.6 ILOAD=1.0A 0.4 ILOAD=0.5A 0.2 0 0.3 0.6 0.9 1.2 1.5 0 1.8 2 4 ILOAD (A) Quiescent Current vs. Temperature 8 Ground Current vs. VIN 50 41 39 45 37 40 Ground Current (µA) Quiescent Current @ 5V (uA) 6 VOUT (V) 35 33 31 29 35 IOUT = 140mA V OUT = 1.5V 30 25 20 15 27 10 25 -45 -5 25 55 85 115 2 3 4 5 6 7 8 VIN (V) Temperature (o C) Ground Current vs. Load Current VOUT vs. Temperature(2.5V) 38.5 2.500 2.495 37.5 Output Voltage (V) G round Current (µA) 38 V IN = 2.5V VOUT = 1.5V 37 36.5 36 35.5 2.490 2.485 2.480 35 34.5 0 0.25 0.5 0.75 1 Load Current (A) 20 1.25 1.5 2.475 -45 -5 25 55 85 115 Temperature (oC) Rev.
