SS6735-38GUTR

SS6735G 500mA Low Dropout Linear Regulator FEATURES Low dropout voltage of 650mV at an output current of 500mA (3.0V output version). Guaranteed 500mA output current. Low ground current of 65µA. Output voltage accuracy of 2% at 1.8V/ 2.0V /2.5V /2.7V/ 3.0V/ 3.3V/ 3.5V/ 3.7V/ 3.8V/ 5.0V/5.2V Only needs 4.7µF output capacitor for stability. Current and thermal limiting. DESCRIPTION The SS6735G is a 3-pin low-dropout linear regulator with superior characteristics, which include zero base current loss, very low dropout voltage, and output voltage accuracy of 2%. Typical ground current remains approximately 65µA, for loads ranging from zero to maximum. Dropout voltage at an output current of 100mA is exceptionally low. Built-in output current limiting and thermal limiting provide maximum protection against fault conditions. Pb-free, RoHS compliant. APPLICATIONS CD-ROM Drivers. LAN Cards. Microprocessors. DRAM Modules. Wireless Communication Systems. Battery Powered Systems. The SS6735G is available in RoHS-compliant SOT-23-3, SOT-223, SOT-89, and TO-252 packages.

Guaranteed by design. Regulation is measured at constant junction temperature, using pulse testing with a low ON time. Current limit is measured by pulsing a short time. Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below the value of the output voltage measured with a 1V differential. 1/15/2005 Rev.2.10 www.SiliconStandard.com 4 of 9 SS6735G TYPICAL PERFORMANCE CHARACTERISTICS 500 600 SS6735-52 400 500 SS6735-33 T=25°C VDROP (mV) 300 VDROP (mV) 150 200 250 300 350 400 450 500 T=25°C 400 300 200 200 100 100 0 50 100 0 0 ILOAD (mA) 0 50 100 Fig. 1 480 460 440 VDROP vs. ILOAD 640 ILOAD (mA) Fig. 2 VDROP vs. ILOAD 150 200 250 300 350 400 450 500 SS6735-52 ILOAD=500mA VDROP (mV) 620 600 580 560 540 520 500 480 SS6735-33 ILOAD=500mA VDROP (mV) 420 400 380 360 340 320 -40 -30 -20 -10 0 10 20 30 40 50 60 70 80 460 -40 -20 0 20 40 60 80 Temperature (°C) Fig. 3 46.0 VDROP vs. Temperature 46.0 Fig. 4 Temperature (°C) VDROP vs. Temperature SS6735-52 Ground Current (µA) 45.5 45.5 45.0 44.5 44.0 43.5 43.0 0 SS6735-33 T=25°C Ground Current (µA) T=25°C 45.0 44.5 44.0 43.5 43.0 0 50 100 150 200 250 300 350 400 450 500 50 100 150 200 250 300 350 400 450 500 ILOAD (mA) ILOAD (mA) Fig. 5 Ground Current vs. ILOAD Fig. 6 Ground Current vs. ILOAD 1/15/2005 Rev.2.10 www.SiliconStandard.com 5 of 9 SS6735G TYPICAL PERFORMANCE CHARACTERISTICS (Continued) 46 45 44 43 42 41 40 -40 46.0 SS6735-52 Ground Current (µA) ILOAD = 500mA SS6735-33 45.5 45.0 44.5 44.0 43.5 43.0 -40 Ground Current (µA) ILOAD = 500mA -20 0 20 40 60 80 -20 0 20 40 60 80 Temperature (°C) Temperature (°C) Fig. 7 700 690 680 670 660 650 640 630 620 610 600 590 580 -40 Ground Current vs. Temperature Fig. 8 Ground Current vs. Temperature SS6735 VIN= 7V VIN= 6V VIN= 5V Current Limit (mA) -20 0 Temperature (°C) 20 40 60 80 Fig. 9 Current Limit vs. Temperature 1/15/2005 Rev.2.10 www.SiliconStandard.com 6 of 9 SS6735G BLOCK DIAGRAM VIN VOUT CURRENT LIMITING ERROR AMP THERMAL SHUTDOWN - + 1.235V Reference + - GND PIN DESCRIPTIONS VOUT PIN - Output pin.
