LRC LR8555-12PRA Low noise 150ma ldo regulator standby mode : 0.1 Datasheet

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