Rev.B.01 11 AME AME8819 n Detailed Description The AME8819 is low-dropout, low quiescent-current linear regulator designed primarily for battery-powered applications. It is available with present output voltage ranging from 1.8V to 3.6V, and can supply loads up to 600mA. n Circuit Limit The AME8819 contains current limiters which monitor and control the pass transistor's Gate voltage, limiting the guaranteed maximum output current to 650mA minimum. The output can be shorted to ground for an indefinite time without damaging the part. n Thermal-Overload Protection Thermal-overload protection limits total power dissipation in the AME8819. 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. Low Dropout 600mA CMOS Regulator n Capacitor Selection and Regulator Stability Use 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 600mA, input and output capacitors should be a minimum of 2.2µF 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 4.7µF or more for up to 600mA load current to ensure stability at temperatures below -10oC. With X7R or X5R dielectrics, 2.2µF is sufficient at all operating temperatures. These regulators are optimized for ceramic capacitors. Tantalum capacitors are not recommended. n PSRR and Operation from sources Other than Batteries The AME8819 is designed to deliver low-dropout voltage and low quiescent currents in battery-powered system. Power-supply rejection ratio is 60dB(Typ.) at 1KHz (see PSRR vs Frequency Curve).When operating from sources other than batteries, PSRR and transient response can be improved by increasing input, output capacitors. 12 Rev.B.01 AME Low Dropout 600mA CMOS Regulator AME8819 Output Voltage vs Temperature Quiesent Current vs Temprature 100 3.06 VOUT = 3.0V IOUT=1mA 3.02 Quiesent Current (V) Output Voltage (V) 3.04 3.00 2.98 IOUT=600mA 2.96 2.94 80 60 IOUT =600mA IOUT=1mA 40 20 2.92 V OUT = 3.0V 2.90 -50 -25 0 +25 +50 +75 +100 0 -50 +125 0 +25 +50 +75 +100 Temperature (oC) Current Limit vs Input Voltage Dropout Voltage vs Load Current 1020 +125 800 VOUT = 3.0V 1015 Dropout Voltage (mV) 700 Current Limit (mA) -25 Temperature ( C) o 1010 1005 1000 995 990 985 980 VOUT = 3.0V IOUT = 600mA TA=125O C 600 500 400 300 TA=25OC 200 TA=-40OC 100 975 970 4 4.5 5 0 0 5.5 Input Voltage (V) 100 200 300 400 500 600 Load Current (mA) Power Supply Rejection Ratio Line Transient Response VIN = 4.0V VOUT = 3.0V 90 80 60 IOUT =100mA 50 40 IOUT =10mA 30 20 10 V OUT (10mV/DIV) PSRR (dB) 70 VIN(1V/DIV) 100 VIN = 4V~5V VOUT = 3.0V IOUT = 1mA 0 1K 10K 100K Frequency (Hz) Rev.B.01 1M TIME (100µSec/DIV) 13 AME Low Dropout 600mA CMOS Regulator AME8819 V OUT = 3.0V IOUT = 1mA~550mA I OUT (200mA/DIV) V OUT (50mV/DIV) Load Transient Response TIME (100µSec/DIV) 14 Rev.B.01 AME Low Dropout 600mA CMOS Regulator AME8819 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 n Tape and Reel Dimension SOT-89 P W AME AME PIN 1 Carrier Tape, Number of Components Per Reel and Reel Size Rev.B.01 Package Carrier Width (W) Pitch (P) Part Per Full Reel Reel Size SOT-89 12.0±0.1 mm 4.0±0.1 mm 1000pcs 180±1 mm 15 AME Low Dropout 600mA CMOS Regulator AME8819 n Tape and Reel Dimension SOT-223 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-223 12.0±0.1 mm 4.0±0.1 mm 2500pcs 330±1 mm SOP-8 P PIN 1 W AME AME AME AME Carrier Tape, Number of Components Per Reel and Reel Size 16 Package Carrier Width (W) Pitch (P) Part Per Full Reel Reel Size SOP-8 12.0±0.1 mm 4.0±0.1 mm 2500pcs 330±1 mm Rev.B.01 AME Low Dropout 600mA CMOS Regulator AME8819 n Package Dimension SOT-89 BOTTOM VIEW D D1 D2 H SIDE VIEW E2 E 3' 10' A1 PIN 1 C e S1 TOP VIEW SYMBOLS A I FRONT VIEW Rev.B.01 MILLIMETERS INCHES MIN MAX MIN MAX A 1.39 1.60 0.05472 0.06299 A1 0.89 1.20 0.03503 0.04724 C 0.35 0.44 0.01378 0.01732 D 4.39 4.60 0.17283 0.18110 D1 1.35 1.83 0.05315 0.07205 E 2.28 2.60 0.08976 0.10236 I 0.36 0.56 0.01256 0.02204 e 3.00 REF 0.11811 REF H 0.70 REF 0.02756 REF S1 1.50 REF 0.05906 REF E2 2.05 2.60 0.08071 0.10236 D2 1.50 1.85 0.05905 0.07283 17 AME Low Dropout 600mA CMOS Regulator AME8819 n Package Dimension SOT-223 Top View Side View SYMBOLS D B1 θ C o 13 (4X) H PIN 1 E e INCHES MIN MAX MIN MAX A1 0.01 0.10 0.0004 0.0039 B 0.60 0.84 0.0236 0.0330 B1 2.90 3.15 0.1140 0.1240 C 0.24 0.38 0.0094 0.0150 D 6.20 6.71 0.2441 0.2640 E 3.30 3.71 0.1299 0.1460 2.30 BSC e Front View 18 MILLIMETERS 0.0906 BSC o 13 (4X) F 1.40 1.80 0.0551 0.0709 F H 6.70 7.30 0.2638 0.2874 A1 θ B 0 o 10 o 0 o 10 o Rev.B.01 AME Low Dropout 600mA CMOS Regulator AME8819 n Package Dimension SOP-8 Top View C E H L D θ PIN 1 Side View Front View o e A1 A A2 7 ( 4 X) SYMBOLS MAX MIN MAX A 1.35 1.75 0.0531 0.0689 A1 0.10 0.30 0.0039 0.0118 1.473 REF 0.05799 REF B 0.33 0.51 0.0130 0.0201 C 0.17 0.25 0.0067 0.0098 D 4.70 5.33 0.1850 0.2098 E 3.80 4.00 0.1496 0.1575 1.27 BSC e 0.05000 BSC L 0.40 1.27 0.0157 0.0500 H 5.80 6.30 0.2283 0.2480 y - 0.10 - 0.0039 θ Rev.B.01 INCHES MIN A2 B MILLIMETERS 0 o 8 o 0 o 8 o 19 www.ame.com.tw E-Mail: [email protected] Life Support Policy: These products of AME, Inc. are not authorized for use as critical components in life-support devices or systems, without the express written approval of the president of AME, Inc.
