AME AME8863 n General Description The AME8863 family of positive, linear regulators feature low quiescent current (30µA typ.) with low dropout voltage, making them ideal for battery applications. The space-saving SOT-26 package is attractive for "Pocket" and "Hand Held" applications. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the "Worst" of operating conditions. An additional feature is a "Power Good" detector, which pulls low when the output is out of regulation. 600mA CMOS LDO n Functional Block Diagram OUT IN Overcurrent Shutdown Thermal Shutdown EN R1 Vrefx110% AMP PG The AME8863 is stable with an output capacitance of 2.2µF or greater. n Features R2 Vref x90% Vref GND l Very Low Dropout Voltage l Guaranteed 600mA Output l Accurate to within 1.5% l 30µA Quiescent Current l Over-Temperature Shutdown n Typical Application l Current Limiting l Short Circuit Current Fold-back l Power Good Output Function INPUT IN l Power-Saving Shutdown Mode PG l Space-Saving SOT-26 l Factory Pre-set Output Voltages l Low Temperature Coefficien l All AME's Lead Free Products Meet RoHS Standards OUT OUTPUT AME8863 GND EN C1 C2 1µF 2.2µF n Applications l Instrumentation l Portable Electronics l Wireless Devices l Cordless Phones l PC Peripherals l Battery Powered Widgets l Electronic Scales Rev.C.03 1 AME AME8863 600mA CMOS LDO n Pin Configuration SOT-26 Top View 6 5 4 AME8863 1.

Rev.C.03 5 AME AME8863 600mA CMOS LDO n Detailed Description n Enable The AME8863 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current protection, thermal shutdown, and power good function. 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 600mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120oC. n Power Good The AME8863 includes the Power Good feature. When the output is not within +10% of the specified voltage, it pulls low. This can occur under the following conditions: 1) Input Voltage too low. 2) During Over-Temperature. The AME8863 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. The AME8863 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. 3) During Over-Current. 4) If output is pulled up. (Note: PG pin is an open-drain output.) n External Capacitors The AME8863 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 0.1µF ceramic capacitor with a 10µF Aluminum Electrolytic. The benefit is low ESR, high capacitance, and low overall cost. 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. 6 Rev.C.03 AME AME8863 600mA CMOS LDO n Characterization Curve Ground Current vs. Input Voltage Load Step (1mA-600mA) 45 Vo(10mV/DIV) 85 OC 35 30 25 O Output C L=2.2µF CIN=2.2µF 25 C 20 IL (200mA/DIV) Ground Current (µ A) 40 15 10 5 0 0 1 2 3 4 5 6 7 I Load 0 8 Input Voltage (V) TIME (20mS/DIV) Drop Out Voltage vs. Output Voltage Power Supply Rejection Ratio 0 Top to Bottom ILOAD=600mA ILOAD=500mA ILOAD=400mA ILOAD=300mA ILOAD=200mA ILOAD=100mA 1200 1000 800 600 -10 Tantalum CL=2.2µF Tantalum C BYP=0 -20 PSRR (dB) Dr op O ut Voltage (mV) 1400 400 100mA -30 -40 -50 10mA 100mA -60 200 -70 0 -80 1 2 3 4 5 6 100 µ A 100 µ A 10 1K Output Voltage (V) 1mA 100K 10M Frequency (Hz) Safe Operating Area Power Supply Rejection Ratio -20 100mA 600 PSRR (dB) Output Current (mA) -30 SOT-2X 100 C L=2.2µF Tantalum CBYP=1000pF 1mA -40 -50 100mA -60 -70 10 0.1 1.0 8.0 Input-Output Voltage Differential (V) Rev.C.03 -80 10 10mA 100µA 100µA 1K 100K 10M Frequency (Hz) 7 AME AME8863 600mA CMOS LDO n Characterization Curve Current Limit Response I OUT (200mA/DIV) V OUT (1V/DIV) Overtemperature Shutdown 0 0 C LOAD =2.2µF C IN=1.0µF RLOAD=3.3Ω VOUTNOM =3.3V IOUT (200mA/DIV) VOUT (1V/DIV) R LOAD=6.6 Ω TIME (0.5Sec/DIV) TIME (2mS/DIV) Enable (2V/DIV) Chip Enable Transient Response C L=2µF R L=10Ω 0 Output (1V/DIV) C LOAD=2.2µF C IN=1µF R LOAD <100mΩ VOUT (1V/DIV) IOUT (200mV/DIV) Short Circuit Response 0 TIME (1mS/DIV) TIME (2mS/DIV) Line Transient Response Quiescent Current vs. Temp. 38 C LOAD=2.2µF ILOAD =1mA VOUTDC=3.3V VINDC=4.5V 36 34 32 30 28 26 TIME (200mS/DIV) 8 Quiescent Current (uA) VOUT (10mV/DIV) V IN (1V/DIV) 40 -20 0 20 40 60 80 Temperature ( o C) Rev.C.03 AME AME8863 600mA CMOS LDO n Date Code Rule Marking Date Code Year A A A W W xxx0 A A A W W xxx1 A A A W W xxx2 A A A W W xxx3 A A A W W xxx4 A A A W W xxx5 A A A W W xxx6 A A A W W xxx7 A A A W W xxx8 A A A W W xxx9 n Tape & Reel Dimension SOT-26 P W AME AME PIN 1 Carrier Tape, Number of Components Per Reel and Reel Size Rev.C.03 Package Carrier Width (W) Pitch (P) Part Per Full Reel Reel Size SOT-26 8.0±0.1 mm 4.0±0.1 mm 3000pcs 180±1 mm 9 AME AME8863 600mA CMOS LDO n Tape & Reel Dimension TSOT-26 P W AME AME PIN 1 Carrier Tape, Number of Components Per Reel and Reel Size 10 Package Carrier Width (W) Pitch (P) Part Per Full Reel Reel Size TSOT-26 8.0±0.1 mm 4.0±0.1 mm 3000pcs 180±1 mm Rev.C.03 AME AME8863 600mA CMOS LDO n Package Dimension SOT-26 Top View Side View SYMBOLS D e MILLIMETERS MIN θ1 1.20REF E H A 0.0472REF L 0.15 0.0000 0.0059 b 0.30 0.55 0.0118 0.0217 D 2.70 3.10 0.1063 0.1220 E 1.40 1.80 0.0551 0.0709 1.90 BSC 2.60 θ1 0.0748 BSC 3.00 0.37REF L A MAX 0.00 H Front View MIN A1 e S1 MAX INCHES 0o 0.10236 0.11811 0.0146REF 10o 0o 10o 0.95REF 0.0374REF MILLIMETERS INCHES A1 S1 b TSOT-26 Top View Side View SYMBOLS MIN MAX MIN MAX A+A1 0.90 1.25 0.0354 0.0492 b 0.30 0.50 0.0118 0.0197 D 2.70 3.10 0.1063 0.1220 E 1.40 1.80 0.0551 0.0709 θ1 E H D e L H S1 1.90 BSC e 2.40 θ1 0 o 10 0.95BSC 0.09449 0.11811 0.0138BSC o 0o 10o 0.0374BSC A1 A S1 3.00 0.35BSC L Front View 0.07480 BSC b Rev.C.03 11 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.
