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 1µA. This pin behaves much like an electronic switch. 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 150mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120oC. The AME8833/8834 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. The AME8833/8834 also incorporates current foldback to reduce power dissipation when the output is short circuited. This feature becomes active when the output drops below 0.8volts, and reduces the current flow by 65%. Full current is restored when the voltage exceeds 0.8 volts. n Adjustable Version AME8834 features a user-adjustable output through an external feedback resister divider. To set the output of AME8834 use the following equation: VOUT=VADJ(1+R1/R2) VADJ=1.225V, use 1% or better resistors n External Capacitors The AME8833/8834 is stable with an output capacitor to ground of 0.22µF 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. A second capacitor is recommended between the input and ground to stabilize Vin. The input capacitor should be at least 1µF to have a beneficial effect. A larger capacitor improves the AC ripple rejection, but also makes the output come up slowly. This "Soft" turnon 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. 8 Rev.H.05 AME High PSRR, 150mA CMOS LDO AME8833/8834 n Characterization Curve Input Current vs. Temperature 70 57. 5 60 57. 0 Input Current @No Load (uA) Input Current (uA) Input Current vs. Input Voltage 50 40 30 20 10 0 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4. 0 4.5 5.0 5.5 56. 5 56. 0 55. 5 55. 0 54. 5 54. 0 -45 6.0 -5 25 55 85 Temperature (oC) Input Voltage (V) Output Voltage vs. Temperature Dropout Voltage vs. Load 2.852 300 o 85 C 2.850 VOUT=2.85V 200 o 55 C 25oC 150 o -5C - 45 oC 100 Output Voltage (V) Dropout Voltage (mV) 250 50 0 0 30 60 90 120 2.844 2.842 2.838 -45 150 25 55 85 Temperature (oC) Output Voltage vs. Load Current Output Voltage vs. Input Voltage 3.0 2.5 Output Voltage (V) 2.845 2.840 2.835 2.830 -5 Load Current (mA) 2.850 Output Voltage (V) 2.846 2.840 2.855 VOUT =2.85V ILOAD=0.1mA 2.0 1.5 1.0 0.5 0 30 60 90 Load Current (mA) Rev.H.05 2.848 120 150 0. 0 0.0 0.5 1.0 1. 5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 Input Voltage (V) 9 AME High PSRR, 150mA CMOS LDO AME8833/8834 n Characterization Curve (Contd.)
