BL8562
150mA Low dropout voltage regulator
Features：
General Description：
BL8562 series is a group of positive
voltage output, low power consumption, low
dropout voltage regulator.
BL8562 can provide output value in the
range of 0.8V~5.0V every 0.1V step. It also
can be customized on command.
BL8562 includes high accuracy voltage
reference, error amplifier, current limit circuit
and output driver module.
BL8562 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%.
BL8562 is available in SOT-23-3 packages
which is lead free..
