General Description：
BL8558 series is a group of positive
voltage output, low power consumption,
low dropout voltage regulator.
BL8558 can provide output value in the
range of 1.2V~4.5V every 0.1V step. It
also can be customized on command.
BL8558 includes high accuracy voltage
reference, error amplifier, current limit
circuit and output driver module with
discharge capability.
BL8558 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%.
BL8558 is available in SOT-23-5,
SOT89-3, SOT23-3, TO92 packages
which are lead free.
