SS6734G 300mA Low Dropout Linear Regulator FEATURES Low dropout voltage of 470mV at an output current of 300mA (3.0V output version). Guaranteed 300mA output current. Low ground current of 55µA. 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 1µF output capacitor for stability. Current and thermal limiting. DESCRIPTION The SS6734G 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 55µA, for loads ranging from zero to maximum. Dropout voltage at an output current of 300mA 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 SS6734G is available in RoHS-compliant SOT-23-3, SOT-89, and TO-92 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 SS6734G TYPICAL PERFORMANCE CHARACTERISTICS 5.40 5.35 5.30 3.50 SS6734-52 3.45 3.40 SS6734-33 V OUT (V) V OUT (V) 5.25 5.20 5.15 5.10 5.05 5.00 -50 3.35 3.30 3.25 3.20 3.15 3.10 -50 -30 -10 10 30 50 70 90 -30 -10 10 30 50 70 90 Temperature (°C) Temperature (°C) Fig. 1 50 VOUT vs. Temperature 48 Fig. 2 VOUT vs. Temperature SS6734-52 SS6734-33 Ground Current (µA) Ground Current (µA) 48 ILOAD=300mA 46 ILOAD=300mA 46 44 44 42 42 ILOAD=100mA 40 40 ILOAD=100mA ILOAD= 0mA ILOAD= 0mA 0 10 20 30 40 50 60 70 80 90 38 -40 -30 -20 -10 38 -40 -30 -20 -10 0 10 20 30 40 50 60 70 80 90 Temperature (°C) Temperature (°C) Fig. 3 60 Ground Current vs. Temperature 60 Fig. 4 Ground Current vs. Temperature SS6734-52 SS6734-33 Ground Current (µA) 40 Ground Current (µA) 0 1 2 3 4 5 6 7 8 9 10 11 12 50 50 40 30 30 20 20 10 10 0 0 0 1 2 3 4 5 6 7 8 9 10 11 12 VIN (V) VIN (V) Fig. 5 Ground Current vs. VIN Fig. 6 Ground Current vs. VIN 1/15/2005 Rev.2.10 www.SiliconStandard.com 5 of 9 SS6734G TYPICAL PERFORMANCE CHARACTERISTICS (Continued) 500 450 400 600 SS6734-52 T= 80°C 500 SS6734-33 T= 80°C T= 50°C T= 20°C VDROP (mV) VDROP (mV) 350 300 250 200 150 100 50 00 T= 50°C T= 20°C T=-40°C 400 300 200 T=-40°C 100 0 50 100 150 200 250 300 350 400 0 50 100 150 200 250 300 350 400 ILOAD (mA) ILOAD (mA) Fig. 7 VDROP vs. ILOAD Fig. 8 VDROP vs. ILOAD 500 490 480 SS6734 VIN = 8V VIN = 7V Crrent Limit (mA) 470 460 450 440 430 420 410 400 -40 VIN = 6V VIN = 5V -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 SS6734G BLOCK DIAGRAM VIN VOUT CURRENT LIMITING ERROR AMP THERMAL SHUTDOWN + + 1.235V Reference - GND PIN DESCRIPTIONS VOUT PIN - Output pin.
