The AME8810 is stable with an output capacitor to ground of 2.2µF 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 600mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120oC. The AME8810 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. The AME8810 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. Rev.A.05 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. 7 AME 600mA CMOS LDO AME8810 n Characterization Curve(For reference only) Ground Current vs. Input Voltage Load Step (1mA-600mA) 45 85 C 35 30 25 O 25 C 20 15 10 5 0 0 1 2 3 4 5 Output VO (5mV/DIV) O 6 7 8 IL(200mA/DIV) Ground Current (µ A) 40 CL =2.2µF C IN =2.2µF I Load 0 TIME(20mS/DIV) Input Voltage (V) Drop Out Voltage vs. Output Voltage Power Supply Rejection Ratio 1400 1000 800 600 -10 Tantalum CL=2.2µF Tantalum C BYP =0 -20 PSRR (dB) Drop Out Voltage (mV) 0 Top to Bottom ILOAD=600mA ILOAD=500mA ILOAD=400mA ILOAD=300mA ILOAD=200mA ILOAD=100mA 1200 400 100mA -30 -40 -50 10mA 100mA -60 200 -70 0 1 2 3 4 5 6 100 µ A 100 µ A 1mA -80 Output Voltage (V) 10 1K 100K 10M Frequency (Hz) Line Transient Response VIN(1V/DIV) Safe Operating Area SOT-223 100 10 0.1 1.0 8.0 Input-Output Voltage Differential (V) 8 VINDC=5.0V CL=2.2µF VO(1mV/DIV) Output Current (mA) 600 TIME (2mS/DIV) Rev.A.05 AME 600mA CMOS LDO AME8810 n Characterization Curve(For reference only) I OUT (200mA/DIV) CL=2.2µF No Filter Overtemperature Shutdown TIME (20ms/DIV) TIME (2mS/DIV) IOUT (200mV/DIV) Short Circuit Response CLOAD=2.2µF CIN=1µF RLOAD<100mΩ VOUT (1V/DIV) VOUT (1V/DIV) IOUT (200mA/DIV) CLOAD=2.2µF CIN=1.0µF RLOAD=3.3Ω VOUTNOM=3.3V 0 TIME (0.5Sec/DIV) Current Limit Response Rev.A.05 0 R LOAD=6.6 Ω VOUT (1V/DIV) Vo (1mV DIV) Noise Measurement TIME (2mS/DIV) 9 AME 600mA CMOS LDO AME8810 n Tape and Reel Dimension SOT-223 P W AME AME PIN 1 Carrier Tape, Number of Components Per Reel and Reel Size 10 Package Carrier Width (W) Pitch (P) Part Per Full Reel Reel Size SOT-223 12.0±0.1 mm 4.0±0.1 mm 2500pcs 330±1 mm Rev.A.05 AME 600mA CMOS LDO AME8810 n Package Dimension SOT-223 Top View Side View SYMBOLS D B1 θ C 13o(4X) H PIN 1 E e 13o(4X) F Rev.A.05 INCHES MIN MAX MIN MAX A1 0.01 0.10 0.0004 0.0039 B 0.60 0.84 0.0236 0.0330 B1 2.90 3.15 0.1140 0.1240 C 0.24 0.38 0.0094 0.0150 D 6.30 6.71 0.2480 0.2640 E 3.30 3.71 0.1299 0.1460 2.30 BSC e Front View A1 MILLIMETERS 0.0906 BSC F 1.40 1.80 0.0551 0.0709 H 6.70 7.30 0.2638 0.2874 θ 0 o 10 o 0 o 10 o B 11 www.ame.com.tw E-Mail: [email protected] Life Support Policy: These products of AME, Inc. are not authorized for use as critical components in life-support devices or systems, without the express written approval of the president of AME, Inc.
