It also can be customized on command. Short Protection Circuit The LC1201 regulator offers circuit protection by means of a built-in foldback circuit. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, the output voltage drops further and output current decreases. When the output pin is shorted, a current of about 60mA flows. CE Pin The IC's internal circuitry can be operated or shutdown via the signal from the CE pin with the LC1201. Note that the LC1201 regulator is “High Active/No Pull-Down”, operations will become unstable with the CE pin open. We suggest that you use this IC with either a VIN voltage or a GND voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin, the operational logic is fixed and the IC will operate normally. Otherwise, supply current may increase as a result of through current in the IC's internal circuitry. Thermal Shutdown When the junction temperature of the built-in driver transistor reaches the temperature limit, the thermal shutdown circuit operates and the driver transistor will be set to OFF. The IC resumes its operation when the thermal shutdown function is released and the IC’s operation is automatically restored because the junction temperature drops to the level of the thermal shutdown release voltage. www.leadchip.com.cn 4 Your final power solution LC1201 TYPICAL PERFORMANCE CHARACTERISTICS Load Regulation Load Regulation (Vout=1.2V) (Vout=1.8V) 1.2 2.0 1.0 Vout (V) Vout (V) 1.5 0.8 0.6 1.0 0.4 0.5 Vin=3.0V Vin=2.2V Vin=1.8V 0.2 0.0 0 100 200 300 Vin=3.3V Vin=2.8V Vin=2.3V 0.0 400 0 100 200 Iout (mA) 300 400 500 Iout (mA) Load Regulation Line Regulation (Vout=3.3V) (Vout=1.2V) 3.5 1.4 1.3 3.0 1.2 Vout (V) Vout (V) 2.5 2.0 1.5 1.1 1.0 0.9 0.8 1.0 0.7 Vin=5.0V Vin=4.3V Vin=3.8V 0.5 0.0 Iout=50mA Iout=10mA Iout=0mA 0.6 0.5 0 100 200 300 400 500 1.0 1.5 2.0 2.5 Iout (mA) 3.5 4.0 4.5 5.0 5.5 6.0 Vin (V) Line Regulation Line Regulation (Vout=1.8V) (Vout=3.3V) 2.0 4.0 1.8 3.5 Vout (V) Vout (V) 3.0 1.6 3.0 1.4 2.5 1.2 Iout=50mA Iout=10mA Iout=0mA 1.0 Iout=50mA Iout=10mA Iout=0mA 2.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 3.0 Vin (V) www.leadchip.com.cn 3.5 4.0 4.5 5.0 5.5 6.0 Vin (V) 5 Your final power solution LC1201 Dropout Voltage vs. Temp Dropout Voltage vs. Temp (Vout=1.8V) 1,300 1,200 1,100 1,000 900 800 700 600 500 400 300 200 100 0 900 800 700 Dropout (mV) Dropout (mV) (Vout=1.2V) 100 200 500 400 300 200 T=-40°C T=25°C T=85°C 0 600 T=-40°C T=25°C T=85°C 100 0 300 0 100 200 Iout (mA) 300 Iout (mA) Dropout Voltage vs. Temp Iq (Vout=3.3V) (Vout=1.2V) 550 1.4 500 1.2 450 1.0 350 Iq (uA) Dropout (mV) 400 300 250 0.8 0.6 200 0.4 150 T=-40°C T=25°C T=85°C 100 50 0 0 100 200 T=-40°C T=25°C T=85°C 0.2 0.0 300 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 Vin (V) Iq Iq (Vout=1.8V) (Vout=3.3V) 1.4 1.4 1.2 1.2 1.0 1.0 Iq (uA) Iq (uA) Iout (mA) 0.8 0.8 0.6 0.6 0.4 0.4 T=-40°C T=25°C T=85°C 0.2 T=-40°C T=25°C T=85°C 0.2 0.0 0.0 2 3 www.leadchip.com.cn 4 Vin (V) 5 6 3.5 4.0 4.5 5.0 5.5 6.0 Vin (V) 6 Your final power solution LC1201 Line Transient Response Load Transient Response Vin=2.8-3.8V, Iout=10mA, Vout=1.8V Iout=1-300mA, Vin=2.8V, Vout=1.8V Vin, 1V/div Iout, 200mA/div Vout, 500mV/div Vout, 500mV/div CE rising response time Rising response time Iout=30mA, Vin=2.8V, Vce=0V-->2V, Vout=1.8V Vin=Vce=2.2V, Iout=30mA, Vout=1.2V Vin, 1V/div Vin, 1V/div Vout, 1V/div Vout, 1V/div Vce, 1V/div Iin, 100mA/div Rising response time Rising response time Vin=Vce=2.8V, Iout=30mA, Vout=1.8V Vin=Vce=4.3V, Iout=30mA, Vout=3.3V Vin, 1V/div Vin, 2V/div Vout, 1V/div Vout, 2V/div www.leadchip.com.cn 7 Your final power solution LC1201 PACKAGE OUTLINE Package SOT-23-5 Devices per reel 3000Pcs DFN1x1-4 Devices per reel 5000Pcs Package Dimension: Unit：mm Package Package Dimension: Unit：mm www.leadchip.com.cn 8 Your final power solution
