Explanation: BL8503 is a series of low dropout voltage and low power consumption three pins regulator. Its application circuit is very simple, which only needs two outside capacitors. It is composed of these modules: high accuracy voltage reference, current limit circuit, error amplifier, output driver and power transistor. Current Limit module can keep chip and power system away from danger when load current is more than 250mA. BL8503 uses trimming technique to assure the accuracy of output value within±2%, at the same time, temperature compensated is elaborately considered in this chip, which makes BL8503’s temperature coefficient within 50ppm/℃。 http://www.belling.com.cn - 6Total 12 Pages 10/24/2016 BL8503 Typical Performance Characteristics: 1.Load regulation Output Voltage VS Output Current(Vout=3.0V) 1.6 Output Voltage (V) Output Voltage (V) Output Voltage VS Output Current(Vout=1.5V) 1.5 1.4 1.3 1.2 1.1 1 0 50 100 150 200 250 3.05 3 2.95 2.9 2.85 2.8 300 0 50 100 150 200 250 300 Output Current (mA) Output Current(mA) 2.Line Regulation Line regulation (Vout=3.0V) 1.51 Output Voltage(V) Output Voltage (V) Line regulation(Vout=1.5V) 1.505 1.5 1.495 1.49 Iout=40mA Iout=6mA 1.485 1.48 1 2 3 4 5 6 7 3.07 3.05 3.03 3.01 2.99 2.97 Iout=40mA Iout=3mA 2.95 2.93 8 3 4 5 Input Voltage(V) 6 7 8 9 10 Input Voltage(V) 3.Dropout Voltage Dropout Voltage (Vout=3.0V) 1.6 Output Voltage(V) Output Voltage(V) Dropout Voltage (Vout=1.5V) 1.5 1.4 1.3 1.2 Iout=100mA Iout=200mA 1.1 1 1.5 1.8 2.1 2.4 2.7 3.05 3.04 3.03 3.02 3.01 3 2.99 2.98 2.97 2.96 3 3 3.2 3.4 3.6 3.8 4 Input Voltage(V) Input Voltage(V) http://www.belling.com.cn Iout=100mA Iout=200mA - 7Total 12 Pages 10/24/2016 BL8503 Input Voltage transient response (Vout=1.5V,Iout=1mA) 4.Input Voltage transient response (Vout=1.5V,Iout=10mA) Cin=Cout=1uF Cin=Cout=1uF Vin=3.5V Vin=3.5V Vin=2.5V Vin=2.5V Input Voltage transient response (Vout=3.0V,Iout=10mA) Input Voltage transient response (Vout=3.0V,Iout=1mA) Cin=Cout=1uF Cin=Cout=1uF Vin=5V Vin=5V Vin=4V Vin=4V 5.Load transient response(Vout=1.5V) Load transient response(Vout=3.0V) Iout=40mA Iout=40mA Iout=1mA http://www.belling.com.cn Iout=1mA - 8Total 12 Pages 10/24/2016 BL8503 Package Outline: Package SOT-89-3 Devices per reel 1000 Unit mm Package Dimension: Taping Specification:(M1:Standard Type,M2:Customized) http://www.belling.com.cn - 9Total 12 Pages 10/24/2016 BL8503 Taping Reel Dimension: SOT-23-3: Package SOT-23-3 Devices per reel 3000 Unit mm Package dimension: http://www.belling.com.cn - 10Total 12 Pages 10/24/2016 BL8503 Taping Specification: Taping reel dimension: http://www.belling.com.cn - 11Total 12 Pages 10/24/2016 BL8503 SOT-23-5: Package SOT-23-5 Devices per reel 3000 Unit mm Package specification: Taping dimension:(M1:Standard Type ,M2:Customized) http://www.belling.com.cn - 12Total 12 Pages 10/24/2016 BL8503 Taping reel dimension: http://www.belling.com.cn - 13Total 12 Pages 10/24/2016
