BL8568CB5ATR18

BL8568 series is a group of positive voltage output, low power consumption, low dropout voltage regulator. BL8568 can provide output value in the range of 1.0V~4.5V every 0.1V step. It also can be customized on command. BL8568 can also work under a wide input voltage ranging from 2.0V to 6V. BL8568 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. BL8568 has excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system. And it uses trimming technique to guarantee output voltage accuracy within ±2%. BL8568 is available in SOT-23-3, SOT-23-5, SC-70-5 and DFN1x1-4 packages which is lead free.
