It is available with present output voltage ranging from 1.2V to 4.5V, and can supply loads up to 300mA. n Shutdown Mode The AME8818 has enable-control-pin. Drive EN low to shutdown OUT. Drive EN to shutdown the entire chip, reducing supply current to 5µA. Connected EN to logic-high or IN for normal operation. n Circuit Limit The AME8818 contains current limiters which monitor and control the pass transistor's Gate voltage, limiting the guaranteed maximum output current to 330mA minimum. The output can be shorted to ground for an indefinite time without damaging the part. Low Dropout 300mA CMOS Regulator n Capacitor Selection and Regulator Stability Use a 1µF capacitor on the AME8818 input and a 1µF capacitor on the OUT. Larger input capacitor values and lower ESR provide better supply noise rejection and line transient response. To reduce output noise and improve load transient voltage dips, use larger output capacitors up to 4.7µF. For stable operation over the full temperature range with load currents up to 300mA, input and output capacitors should be a minimum of 1µF by X7R. Note that some ceramic dielectrics large capacitance and ESR variation with temperature. With dielectrics such as Z5U and Y5V, it may be necessary to use 2.2µF or more for up to 300mA load current to ensure stability at temperatures below -10oC. With X7R or X5R dielectrics, 1µF is sufficient at all operating temperatures. These regulators are optimized for ceramic capacitors. Tantalum capacitors are not recommended. Bypass capacitor can be in between 0.1µF~0.001µF. A larger capacitor improves AC ripple rejection, but also make the output come up slowly. n Thermal-Overload Protection n Adjustable Version Thermal-overload protection limits total power dissipation in the AME8818. When the junction temperature arrive TJ = 160oC approximately, the thermal sensor signals the shutdown logic, turning off the pass transistor and allowing the IC to cool. The adjustable version uses external feedback resistors to generate an output voltage anywhere from 0.98V to 4.5V. VADJ is trimmed to 0.98V and VOUT is given by the equation: VOUT = VADJ ( 1 + R1 / R2 ) n PSRR and Operation from sources Other than Batteries The AME8818 is designed to deliver low-dropout voltage and low quiescent currents in battery-powered system. Power-supply rejection ratio is 60dB (Typ.) at 1KHz. When operating from sources other than betteries, PSRR and transient response can be improved by increasing input, output and bypass capacitors(see PSRR vs Frequency Curve). Rev.D.06 Feedback resistors R1 and R2 should be high enough to keep quiescent current low, but increasing R1 + R2 will reduce stability. In general, R1 and R2 in the 10's of kΩ will produce adequate stability, given reasonable layout precautions. To improve stability characteristics, keep parasitics on the ADJ pin to a minimum, and lower R1 and R2 values. 13 AME Low Dropout 300mA CMOS Regulator AME8818 n Characterization Curve(For reference only) VOUT vs Temperature Quiesent Current vs Temperature 100 3.05 VOUT = 3.0V VOUT = 3.0V V OUT (V) 3.03 3.02 IOUT =1mA 3.01 3.00 80 Quiesent Current (µA) 3.04 IOUT=300mA 2.99 60 I OUT=300mA IOUT =1mA 40 20 2.98 2.97 -50 -25 0 +25 +50 +75 +100 0 - 50 +125 Temperature ( oC) -25 0 +25 +50 +75 +100 +125 Temperature (oC) EN Pin Shutdown Threshold Voltage vs Current Limit vs Input Voltage Temperature 750 VOUT = 1.2V 700 1.25 Current Limit (mA) EN Pin Shutdown Threshold Voltage (V) 1.50 1.00 0.75 V OUT = 3.0V 650 600 550 500 450 0.50 400 0.25 -50 -25 0 +25 +50 +75 +100 350 4.0 +125 4.5 o 100 400 90 VOUT = 3.0V IOUT = 300mA 350 TA=125 C 300 IOUT =10mA VOUT = 1.2V CBYP = 0.1µF IOUT =1mA 80 O 70 PSRR (dB) Dropout Voltage (mV) 5.5 Power Supply Rejection Ratio Dropout Voltage vs Load Current 250 200 150 60 IOUT =100mA 50 40 30 TA=25O C 100 20 T A=-40OC 50 0 0 50 100 150 200 Load Current (mA) 14 5.0 Input Voltage (V) Temperature ( C) 10 250 300 0 1K 10K 100K 1M Frequency (Hz) Rev.D.06 AME Low Dropout 300mA CMOS Regulator AME8818 n Characterization Curve(For reference only) Power Supply Rejection Ratio Line Transient Response 90 VOUT = 3.3V CBYP = 0.1µF I OUT =10mA 80 60 IOUT =1mA 50 40 VIN = 4V~5.5V VOUT = 3.3V IOUT = 1mA IOUT =100mA VIN(2V/DIV) PSRR (dB) 70 VOUT (50mV/DIV) 100 30 20 10 0 1K 10K 100 K 1M TIME (100µSec/DIV) Frequency (Hz) Start Up delay time EN (5V/DIV) VOUT = 3.3V IOUT = 1mA~250mA VOUT (2V/DIV) IOUT (100mA/DIV) VOUT (50mV/DIV) Load Transient Response TIME (40µSec/DIV) VIN = 5V VOUT = 3.3V IOUT = 1mA CBYP = 0µF TIME (10µSec/DIV) VIN = 5V VOUT = 3.3V I OUT = 1mA C BYP = 0µF VOUT (2V/DIV) EN(5V/DIV) EN Pin shutdown Response TIME (20µSec/DIV) Rev.D.06 15 AME Low Dropout 300mA CMOS Regulator AME8818 n Date Code Rule Month Code 1: January 7: July 2: February 8: August 3: March 9: September 4: April A: October 5: May B: November 6: June C: December A A A A A A A A A A A A A A A A A A A A Marking A M A M A M A M A M A M A M A M A M A M X X X X X X X X X X X X X X X X X X X X Year xxx0 xxx1 xxx2 xxx3 xxx4 xxx5 xxx6 xxx7 xxx8 xxx9 For SC-70 (SC-82) Package Only Marking 16 Date Code Year 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.D.06 AME Low Dropout 300mA CMOS Regulator AME8818 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 Rev.D.06 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 17 AME Low Dropout 300mA CMOS Regulator AME8818 n Tape and Reel Dimension (Contd.)
