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. www.SiliconStandard.com 4 of 9 SS6734G TYPICAL PERFORMANCE CHARACTERISTICS 5.40 3.50 SS6734-52 5.30 3.40 5.25 3.35 5.20 5.15 3.30 3.25 5.10 3.20 5.05 3.15 5.00 -50 -30 SS6734-33 3.45 V OUT (V) V OUT (V) 5.35 -10 10 30 50 70 3.10 -50 90 -30 -10 Temperature (°C) Fig. 1 Fig. 2 VOUT vs. Temperature Ground Current (µA) Ground Current (µA) ILOAD=300mA 46 44 42 ILOAD=100mA 40 70 90 VOUT vs. Temperature ILOAD=300mA 46 44 42 ILOAD=100mA 40 ILOAD= 0mA 38 -40 -30 -20 -10 0 ILOAD= 0mA 38 -40 -30 -20 -10 10 20 30 40 50 60 70 80 90 Fig. 3 0 10 20 30 40 50 60 70 80 90 Temperature (°C) Temperature (°C) Ground Current vs. Temperature Fig. 4 60 Ground Current vs. Temperature 60 SS6734-33 SS6734-52 50 Ground Current (µA) Ground Current (µA) 50 SS6734-33 SS6734-52 40 30 20 10 0 30 48 50 48 10 Temperature (°C) 50 40 30 20 10 0 1 2 3 4 5 6 7 8 9 10 11 12 0 0 1 2 VIN (V) Fig. 5 1/15/2005 Rev.2.10 3 4 5 6 7 8 9 10 11 12 VIN (V) Ground Current vs. VIN Fig. 6 www.SiliconStandard.com Ground Current vs. VIN 5 of 9 SS6734G TYPICAL PERFORMANCE CHARACTERISTICS (Continued) 600 500 450 SS6734-52 SS6734-33 T= 80°C 350 VDROP (mV) 400 VDROP (mV) T= 80°C 500 T= 50°C 300 250 T= 20°C 200 T=-40°C 150 T= 50°C 400 300 T= 20°C 200 T=-40°C 100 100 50 00 0 50 100 150 200 250 300 350 400 0 50 100 Fig. 7 VDROP vs. ILOAD 150 200 250 300 350 400 ILOAD (mA) ILOAD (mA) Fig. 8 VDROP vs. ILOAD 500 490 SS6734 Crrent Limit (mA) 480 VIN = 8V 470 VIN = 7V 460 450 440 430 VIN = 6V 420 410 400 -40 VIN = 5V -20 0 20 40 60 80 Temperature (°C) Fig. 9 1/15/2005 Rev.2.10 Current Limit vs. Temperature 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.
