Rev.F.04 9 AME AME8822 High PSRR, 250mA CMOS LDO Detailed Description Enable The AME8822 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current protection, and thermal shutdown. The Enable Pin is normally pull-high. When activated pulled low, the PMOS pass transistor shuts off, and all internal circuits are powered down. In this state, the stand by current is less than 1μA. This pin can’ t be floating. 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 250mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 130oC. The AME8822 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. External Capacitors The AME8822 is stable with an output capacitor to ground of 1μF or larger. 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. 10 Rev.F.04 AME AME8822 High PSRR, 250mA CMOS LDO Dropout Voltage vs Temperature Output Impedance vs Frequency 700 2.0 650 1.8 Output Impedance (Ω) Dropout Voltage (mV) 600 550 500 450 400 350 300 250 200 150 VIN =2.8V Io=250mA 100 -25 -10 5 20 35 50 65 o 80 95 1.4 1.2 1.0 IO=50mA 0.8 0.6 0.4 I O=100mA 0.2 50 0 -40 1.6 0.0 10 110 125 100 1000 Output Voltage vs Load Current 100000 1000000 Output Voltage vs Temperature 1.815 1.820 IO =1mA VIN =2.8V Output Voltage (V) 1.815 Output Voltage (V) 10000 Frequency (Hz) Temperature ( C) 1.810 1.805 1.800 1.795 1.790 1.810 IO=250mA 1.805 1.800 1.795 1.785 VIN =2.8V 1.780 0 50 100 150 200 1.790 -40 250 Load Current (mA) 20 35 50 100 Input Voltage (V) VIN =2.8V 65 80 95 110 125 5.3 4.3 0 50 0 -50 Output Voltage (mV) Output Voltage Output Current (mV) (mA) 5 Line Transient Response 200 Time (µs) Rev.F.04 -10 Temperature (o C) Load Transient Response ∆i =25mA/ µs ∆t -25 20 -20 Time (µs) 11 AME AME8822 High PSRR, 250mA CMOS LDO Quiescent Current vs Temperature Quiescent Current (µA) 40 35 30 25 20 15 10 5 0 -40 -25 -10 5 20 35 50 65 80 95 110 125 Temperature (oC) Rising Time 3.8V 3.3V EN VOUT 20µs/div 12 Rev.F.04 AME AME8822 High PSRR, 250mA CMOS LDO n Date Code Rule For SOT-23/TSOT-23A/SOT-25/TSOT-25A Package Only Marking Date Code Year For DFN-4A Package Only w: Work Week Code A A A W W xxx0 A: 01&02 K: 21&22 U: 41&42 A A A W W xxx1 B: 03&04 L: 23&24 V: 43&44 A A A W W xxx2 C: 05&06 M: 25&26 W: 45&46 A A A W W xxx3 D: 07&08 N: 27&28 X: 47&48 A A A W W xxx4 E: 09&10 O: 29&30 Y: 49&50 A A A W W xxx5 F: 11&12 P: 31&32 Z: 51&52 A A A W W xxx6 G: 13&14 Q: 33&34 A A A W W xxx7 H: 15&16 R: 35&36 A A A W W xxx8 I: 17&18 S: 37&38 A A A W W xxx9 J: 19&20 T: 39&40 Date Code Year For SC-70 Package Only Marking w: Work Week Code A A A W xxx0 A: 01&02 K: 21&22 U: 41&42 A A A W xxx1 B: 03&04 L: 23&24 V: 43&44 A A A W xxx2 C: 05&06 M: 25&26 W: 45&46 A A A W xxx3 D: 07&08 N: 27&28 X: 47&48 A A A W xxx4 E: 09&10 O: 29&30 Y: 49&50 A A A W xxx5 F: 11&12 P: 31&32 Z: 51&52 A A A W xxx6 G: 13&14 Q: 33&34 A A A W xxx7 H: 15&16 R: 35&36 A A A W xxx8 I: 17&18 S: 37&38 A A A W xxx9 J: 19&20 T: 39&40 Rev.F.04 13 AME AME8822 High PSRR, 250mA CMOS LDO n Tape and Reel Dimension SOT-23 P W AME AME PIN 1 Carrier Tape, Number of Components Per Reel and Reel Size Package Carrier Width (W) Pitch (P) Part Per Full Reel Reel Size SOT-23 8.0±0.1 mm 4.0±0.1 mm 3000pcs 180±1 mm SOT-25 P W AME AME PIN 1 Carrier Tape, Number of Components Per Reel and Reel Size 14 Package Carrier Width (W) Pitch (P) Part Per Full Reel Reel Size SOT-25 8.0±0.1 mm 4.0±0.1 mm 3000pcs 180±1 mm Rev.F.04 AME AME8822 High PSRR, 250mA CMOS LDO n Tape and Reel Dimension (Contd.)
