For outputs below 2.5V, dropout voltage is the input-to-output voltage differential with the minimum input voltage 2.6V Note 2) Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the load current plus the ground pin current. 2011. 5. 27 Revision No : 1 4/9 KIC3211 Series TYPICAL CHARACTERISTICS 1) OUTPUT VOLTAGE vs OUTPUT CURRENT (TOPR = 25℃) KIC3211SN28 1.4 OUTPUT VOLTAGE VOUT (V) OUTPUT VOLTAGE VOUT (V) KIC3211SN12 1.2 3.5V 1.0 2.5V 0.8 0.6 2.2V 1.7V 0.4 0.2 1.4 1.2 3.8V 4.8V 1.0 0.8 3.5V 0.6 3.1V 0.4 0.0 0.0 0 100 200 300 400 0 500 OUTPUT CURRENT IOUT (mA) 100 200 300 400 500 OUTPUT CURRENT IOUT (mA) OUTPUT VOLTAGE VOUT (V) KIC3211SN40 4.5 4.0 5.0V 3.5 6.0V 3.0 2.5 4.5V 2.0 4.3V 1.5 1.0 0.5 0.0 0 100 200 300 400 500 OUTPUT CURRENT IOUT (mA) 2) OUTPUT VOLTAGE vs INPUT VOLTAGE (TOPR = 25℃) KIC3211SN28 1.4 OUTPUT VOLTAGE VOUT (V) OUTPUT VOLTAGE VOUT (V) KIC3211SN12 1.3 1.2 1.1 1.0 0.9 IOUT = 1mA IOUT = 30mA 0.8 IOUT = 100mA 2.8 2.7 2.6 2.5 2.4 2.3 IOUT = 1mA 2.2 IOUT = 30mA 2.1 IOUT = 100mA 2.0 0.7 1 2 3 4 5 INPUT VOLTAGE VIN (V) 2011. 5. 27 2.9 Revision No : 1 6 2 3 4 5 6 INPUT VOLTAGE VIN (V) 5/9 KIC3211 Series KIC3211SN40 4.2 4.0 3.8 3.6 3.4 IOUT = 1mA 3.2 IOUT = 30mA IOUT = 100mA 3.0 1 2 3 4 5 6 INPUT VOLTAGE VIN (V) 3) SUPPLY CURRENT vs INPUT VOLTAGE (TOPR = 25℃) KIC3211SN12 KIC3211SN28 90 90 80 80 70 70 60 60 50 50 40 40 30 30 20 20 10 10 0 0 0 1 2 3 4 5 6 INPUT VOLTAGE VIN (V) 0 1 2 3 4 5 6 INPUT VOLTAGE VIN (V) KIC3211SN40 90 80 70 60 50 40 30 20 10 0 0 1 2 3 4 5 6 INPUT VOLTAGE VIN (V) 2011. 5. 27 Revision No : 1 6/9 KIC3211 Series 4) OUTPUT VOLTAGE vs TEMPERATURE KIC3211SN12 KIC3211SN28 1.23 2.86 1.22 2.84 1.21 2.82 1.20 2.80 1.19 2.78 1.18 2.76 1.17 1.16 -40 -15 10 35 60 85 60 85 2.74 -40 -15 10 35 60 85 KIC3211SN40 4.08 4.06 4.04 4.02 4.00 3.98 3.96 3.94 3.92 -40 2011. 5. 27 -15 10 35 Revision No : 1 7/9 KIC3211 Series 5) RIPPLE REJECTION vs FREQUENCY(CIN = none) KIC3211SN12 KIC3211SN12 90 90 80 80 70 70 60 60 50 50 40 40 30 30 IOUT = 1mA 20 10 0 0.1 IOUT = 100mA 1 10 100 0 0.1 90 80 80 70 70 60 60 50 50 40 40 30 IOUT = 100mA 1 10 100 10 0 0.1 IOUT = 30mA 3.8 IOUT = 100mA 1 10 100 KIC3211SN40 90 90 80 80 70 70 60 60 50 50 40 40 30 30 IOUT = 1mA 20 2011. 5. 27 100 IOUT = 1mA 20 IOUT = 30mA 3.8 KIC3211SN40 0 0.1 10 30 IOUT = 1mA 20 10 IOUT = 100mA 1 KIC3211SN28 90 0 0.1 IOUT = 30mA 10 KIC3211SN28 10 IOUT = 1mA 20 IOUT = 30mA IOUT = 100mA 1 10 Revision No : 1 IOUT = 1mA 20 IOUT = 30mA 5.0 100 10 0 0.1 IOUT = 30mA 5.0 IOUT = 100mA 1 10 100 8/9 KIC3211 Series 6) INPUT LINE TRANSIENT RESPONSE(IOUT = 30mA, tr = tf = 5us, CIN / COUT = Ceramic 1.0㎌) KIC3211SN12 KIC3211SN28 1.25 1.24 Input Voltage 4 2.85 3 2.84 6 5 Input Voltage 1.23 2 2.83 4 1.22 1 2.82 3 0 2.81 1.21 2 Output Voltage 2.80 1.20 1.19 0 Output Voltage 10 20 30 40 50 60 70 80 2.79 0 90 100 10 20 30 40 50 60 70 80 1 0 90 100 7) LOAD TRANSIENT RESPONSE (tr = tf = 5us, CIN / COUT = Ceramic 1.0㎌) 1.45 150 1.40 100 2.85 150 2.84 100 Input Voltage Input Voltage 1.35 50 2.83 50 1.30 0 2.82 0 2.81 1.25 Output Voltage 1.20 1.15 0 2011. 5. 27 (mA) KIC3211SN28 (mA) KIC3211SN12 2 4 6 8 10 12 14 Revision No : 1 16 18 20 Output Voltage 2.80 2.79 0 2 4 6 8 10 12 14 16 18 20 9/9
