产品简介
BL8078 series is a group of positive voltage output, low power consumption, low dropout voltage regulator. It can provide 150mA output current when input / output voltage differential drops to 400mV (Vout= 5V), and it also provides foldback short-circuit protection, thermal protection and output current limit function. The very low power consumption of BL8078 (Iq=2.5uA)can greatly improve natural life of batteries.
BL8078 can provide output value in the range of 1.2V~5.0V in 0.1V steps. It also can customize on command.
BL8078 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module.
BL8078 has well load transient response and good temperature characteristic, And it uses trimming technique to guarantee output voltage accuracy within±2%.
