LR8555
Low noise 150mA LDO regulator
Low power consumption,low dropout voltage regulator.
LR8555 series is a group of positive voltage output
LR8555 can provide output value in the range of 1.2~5V
LR8555 includes high accuracy voltage reference,error
every 0.1V step.It also can be customized on command.
amplifier,current limit circuit and output driver module.
and good temperature characteristcs,which can assure
LR8555 has excellent load and line transient response
the stabllity of chip and power system.And it uses trimming
LR8555 is avilable in SOT23-5,SC70-5 packages which
technique to output voltage accuracy with ± 2%.
is lead free.It also can available in these packages with lead.
