DESCRIPTION
The BL9180 dual, low noise, low-dropout regulator
supplying up to 300mA output current at each
channel. 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 package
which is Lead(Pb)-free.
