BL8075 16V 500mA Low Consumption Linear Regulator DESCRIPTION FEATURES BL8075 series is a group of positive voltage output, low power consumption, low dropout voltage regulator. It can provide 300mA output current when input / output voltage differential drops to 600mV (Vout= 3.3V), and it also provides foldback short-circuit protection, thermal protection and output current limit function. The very low power consumption of BL8075 (Iq=10uA)can greatly improve natural life of batteries. BL8075 can provide output value in the range of 1.2V~5.0V in 0.1V steps. It also can customize on command. Low Power Consumption: 10uA(Typ.) Maximum Output Current: 500mA Small Dropout Voltage 600mV@300mA (Vout=3.3V) 1.2V@500mA (Vout=3.3V) Input Voltage Range: 3V~16V Output Voltage Range: 1.2V~5.0V (customized on command in 0.1V steps) Highly Accurate:±2%(±1% customized) Output Current Limit: 650mA APPLICATIONS BL8075 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. BL8075 has well load transient response and good temperature characteristic, And it uses trimming technique to guarantee output voltage accuracy within±2%.

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 500mA. BL8075 uses trimming technique to assure the accuracy of output value within±2%, at the same time, temperature compensation is elaborately considered in this chip, which makes BL8075’s temperature coefficient within ±100ppm/℃。 www.belling.com.cn 3 BL8075 TYPICAL PERFORMANCE CHARACTERISTICS Line Regulation 4.0 4.0 3.5 3.5 3.0 3.0 2.5 2.5 Vout(V) Vout(V) Load Regulation 2.0 2.0 1.5 1.5 1.0 1.0 0.5 0.5 0.0 0.0 0 100 200 300 Iout(mA) 400 0 500 4 16 Iq 120 1400 Vout=3.3V Vout=3.3V 1200 100 1000 80 Iq(uA) Dropout(mV) 12 Vin(V) Dropout 800 60 600 40 400 20 200 0 0 0 100 200 300 400 500 0 Iout(mA) Current Limit 3.0 2.5 2.0 1.5 1.0 0.5 0.0 0 100 200 300 400 500 600 700 Iout(mA) www.belling.com.cn 4 8 Vin(V) 3.5 Vout(V) 8 4 12 16 BL8075 Line transient response Load transient response Vin=5V~6V, Iout=10mA Ch1—Vin, Ch2—Vout Vin=5V, Iout=5mA~150mA Ch2—Vout, Ch4—Iout PACKAGE LINE Package SOT-23-5 Devices per reel 3000Pcs Package dimension： www.belling.com.cn 5 Unit mm BL8075 Package SOT-89-3 Devices per reel 1000Pcs Package Dimension: www.belling.com.cn 6 Unit mm
