For outputs below 2.5V, output voltage is stabilized from 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. 2007. 6. 19 Revision No : 5 3/5 KIC3210T-018 ~ KIC3210T-035 Fig. 1 R.R GROUND CURRENT IGND (µA) 70 100µA* Fig. 2 VIN - IGND 140 IOUT = 100µA 60 50mA* 120 100 80 60 40 20 0 0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 50 R.R (dB) 40 30 20 10 0 101 150mA* 100mA* *IOUT COUT=1µF Ceramic 102 103 104 105 106 FREQUENCY (Hz) INPUT VOLTAGE VIN (V) Fig. 3 VIN - VOUT OUTPUT VOLTAGE VOUT (V) DROP VOLTAGE VDROP (mV) 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0 0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 IOUT =100µA IOUT =150mA Fig. 4 Ta - VDROP 0.14 0.12 0.1 0.8 0.6 0.4 0.2 0 -40 -20 0 20 40 60 80 100 120 140 IOUT = 100µA INPUT VOLTAGE VIN (V) TEMPERTURE Ta ( C) Fig. 5 Ta - VOUT OUTPUT VOLTAGE VOUT (V) 3.05 3.04 3.03 3.02 3.01 3.00 2.99 2.98 2.97 2.96 2.95 -40 -20 0 20 40 60 80 IOUT = 100µA Fig. 6 Line Transient Response OUTPUT VOLTAGE INPUT VOLTAGE (50mV/div) (1V/div) 5V 4V CIN = 1µF Ceramic COUT = 1µF Ceramic CBYP = 0.01µF IOUT=100µA 100 120 140 TIME (400µs/div) TEMPERTURE Ta ( C) 2007. 6. 19 Revision No : 5 4/5 KIC3210T-018 ~ KIC3210T-035 OUTPUT VOLTAGE ENABLE VOLTAGE (1V/div) (1V/div) OUTPUT CURRENT OUTPUT VOLTAGE (100mV/div) (50mV/div) Fig. 7 Load Transient Response Fig. 8 ON/OFF Control Pin Delay 150mA CIN = 1µF Ceramic COUT = 1µF Ceramic CBYP = 0.01µF VIN = 4V CIN = 1µF Ceramic COUT = 1µF Ceramic CBYP = 0.01µF IOUT=100µA 100mA TIME (4µs/div) TIME (10µs/div) Fig. 9 Shutdown Delay OUTPUT VOLTAGE ENABLE VOLTAGE (1V/div) (1V/div) CIN = 1µF Ceramic COUT = 1µF Ceramic CBYP = 0.01µF VIN = 4V TIME (400µs/div) 2007. 6. 19 Revision No : 5 5/5
