AME8800 / 8811 300mA CMOS LDO n Detailed Description n External Capacitors The AME8800/8811 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current protection, and thermal shutdown. The AME8800/8811 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 0.1uF ceramic capacitor with a 10uF 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 300mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120oC. The AME8800/8811 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. The AME8800/8811 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 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. 13 AME, Inc. 300mA CMOS LDO AME8800 / 8811 Load Step ( 1mA-300mA) Ground Current vs. Input Voltage Vo(5mV/DIV) 45 35 85 O C 30 C L =2.2µF C I N =2.2µF Output 25 25 O C 20 IL(200mA/DIV) µA) Ground Current (µ 40 15 10 5 IL o a d 0 0 0 1 2 3 4 5 6 7 TIME( 20mS/DIV) 8 Input Voltage (V) Drop Out Voltage vs Output Voltage Drop Out Voltage vs Load Current 250 250 200 Dropout Voltage (mV) Drop Out Voltage (mV) 300 IL O A D = 3 0 0 m A 150 IL O A D = 2 0 0 m A 100 IL O A D = 1 0 0 m A 50 200 150 100 50 0 0 2.5 2.75 3 3.25 3.5 3.75 4 0 ILOAD (400mA/DIV) -10 -40 200 250 300 R L O A D =100Ω R S H O R T =0.1Ω 0 10mA 100mA -60 -70 -80 1.0E+01 14 150 100 µA 1.0E+03 100 µA 1.0E+05 Frequency (Hz) 1mA 1.0E+07 VOUT (1V/DIV) PSRR (dB) 100mA -30 -50 100 Short Circuit Response Power Supply Rejection Ratio 0 C L =2.2µF Tantalum C B Y P =0 50 Load Current (mA) Output Voltage (V) -20 Top to bottom V O U T =2.5V V O U T =2.8V V O U T =3.0V V O U T =3.3V V O U T =3.5V V O U T =3.8V 0 TIME (2mS/DIV) AME, Inc.
