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 SS6735G TYPICAL PERFORMANCE CHARACTERISTICS 500 600 SS6735-52 SS6735-33 500 T=25°C VDROP (mV) VDROP (mV) 400 300 200 T=25°C 400 300 200 100 100 0 0 50 100 150 200 250 300 350 400 450 500 0 ILOAD (mA) Fig. 1 50 100 200 SS6735-52 620 SS6735-33 440 ILOAD=500mA 600 ILOAD=500mA VDROP (mV) 460 420 400 380 350 400 450 500 580 560 540 520 480 320 -40 -30 -20 -10 0 10 20 30 40 50 60 70 460 -40 80 -20 Temperature (°C) Fig. 3 Fig. 4 VDROP vs. Temperature 0 20 40 60 80 Temperature (°C) VDROP vs. Temperature 46.0 46.0 SS6735-52 Ground Current (µA) 45.5 T=25°C 45.0 44.5 44.0 45.5 SS6735-33 T=25°C 45.0 44.5 44.0 43.5 43.5 50 100 150 200 250 300 350 400 450 500 43.0 0 50 100 Fig. 5 150 200 250 300 350 400 450 500 ILOAD (mA) ILOAD (mA) 1/15/2005 Rev.2.10 300 500 340 43.0 0 250 640 360 Ground Current (µA) 150 ILOAD (mA) Fig. 2 VDROP vs. ILOAD VDROP vs. ILOAD 480 VDROP (mV) 0 Ground Current vs. ILOAD Fig. 6 www.SiliconStandard.com Ground Current vs. ILOAD 5 of 9 SS6735G TYPICAL PERFORMANCE CHARACTERISTICS (Continued) 46.0 SS6735-33 SS6735-52 45 Ground Current (µA) Ground Current (µA) 46 ILOAD = 500mA 44 43 42 45.5 ILOAD = 500mA 45.0 44.5 44.0 43.5 41 40 -40 -20 0 20 40 60 80 43.0 -40 Fig. 7 -20 0 20 40 60 80 Temperature (°C) Temperature (°C) Ground Current vs. Temperature Fig. 8 Ground Current vs. Temperature 700 690 SS6735 VIN= 7V Current Limit (mA) 680 670 660 VIN= 6V 650 640 VIN= 5V 630 620 610 600 590 580 -40 -20 Fig. 9 1/15/2005 Rev.2.10 0 20 40 Temperature (°C) 60 80 Current Limit vs. Temperature 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.
