Rev.C.01 9 AME AME8853A n Detailed Description The AME8853A family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current protection thermal shutdown, and Power Good detection circuitry. 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 300mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops more 20oC. High PSRR, Low Noise, 300mA CMOS Regulator Capacitor Selection and Regulator Stability The maximum output power of the AME8853A is limited by the maximum power dissipation of the package. By calculation the power dissipation of the package as a function of the input voltage, output voltage and output current, the maximum input voltage can be obtained. The maximum power dissipation should not exceed the package’ s maximum power rating. PMAX = (V IN(MAX) -V OUT) x IOUT Where: VIN(MAX) = maximum input voltage PMAX = maximum power dissipation of the package Capacitor Selection and Regulator Stability The AME8853A is stable with an output capacitor to ground of 1µF 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. A second capacitor is recommended between the input and ground to stabilize V IN. The input capacitor should be at least 0.1µF to have a beneficial effect. Enable Pin The Enable Pin is pull-low. When activated pulled low, the MOS pass transistor shuts off, and all internal circuits are powered down. In this state, the stand by current is less than 1µA. 10 Rev.C.01 AME High PSRR, Low Noise, 300mA CMOS Regulator AME8853A n Characterization Curve Output Voltage Output Voltage 1 .050 4 .45 1 .040 Output Voltag e (V) Output Voltage (V) 4 .40 1 .030 1 .020 1 .010 1 .000 0 .990 0 .980 VIN = 2.8V V OUT = 1.0V IOUT = 1mA 0 .970 0 .960 0 .950 -40 -25 -10 +5 4 .35 4 .30 4 .25 V IN = 5.3V V OUT = 4.3V IOUT = 1mA 4 .20 4 .15 -40 +20 + 35 + 50 + 65 +80 + 95 + 110 +125 Temperature( OC) -25 -10 +5 100 100 90 90 80 80 70 70 60 60 IQ(µA) IQ(µA) +50 +65 + 80 + 95 +110 + 125 Quiescent Current 50 40 30 50 40 30 20 20 VOUT = 1.0V 10 VOUT = 4.3V 10 0 -40 -25 -10 +5 + 20 + 35 +50 0 -40 +65 + 80 + 95 +110 +125 Temperature(OC) 900 900 Current Limit (mA) 1000 800 700 600 500 VOUT = 1.0V 3.8 Input Voltage Rev.C.01 +5 + 20 +35 +50 + 65 + 80 + 95 +110 + 125 800 700 600 500 4.8 VOUT = 4.3V 400 300 2 .8 -10 Current Limit vs. Input Voltage 1000 400 -25 Temperature(O C) Current Limit vs. Input Voltage Current Limit (mA) +35 O Quiescent Current 300 +20 Temperature( C) 5.5 5.3 5.4 5 .5 Input Voltage 11 AME High PSRR, Low Noise, 300mA CMOS Regulator AME8853A n Characterization Curve (Contd.)
