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