The output voltage for each regulator is set independently by trimming. Voltages are selectable in 50mV steps within a range of 1.2V to 3.3V by operating from a 2V to 6V input. The BL9180 includes two independent logic-controlled shutdown inputs and allows the output of each regulator to be turned off independently. When both outputs shutdown simultaneously, the chip will be turn off and consumes nearly zero operation current which is suitable for battery-power devices. The BL9180 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. The BL9180 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 ±1% or ±2%. The BL9180 is available in SOT-23-6 and ESOP-8 package which is Lead(Pb)-free.
