DESCRIPTION
BL8064 series is a group of positive voltage output, low power consumption, low dropout voltage, three termi nal regulator. It can provide 200mA output current when input / output voltage differential drops to 430mV（Vout = 2.8V）, The very l ow power consumption of BL8064 （Iq=1.0uA）can greatly improve natural life of batteries. BL8064 can provide output value in the range of 1.1V~5.5V in 0.1V steps. It also can be customized on command. BL8064 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. BL8064 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 w hen load current is more than 200mA. BL8064 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 BL8064’s temperature coefficient within 100ppm/C。
