| ACE505 Technology Description Low noise 150mA LDO regulator ACE505 series is a group of positive voltage output, low power consumption, low dropout voltage regulator. ACE505 can provide output value in the range of 1.2V~5.0V every 0.1V step. It also can be customized on command. ACE505 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. ACE505 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 within2%. ACE505 is available in SOT-23-5, SC-70-5 packages which is lead free. It also can available in these packages with lead. * * * * * * * * * * * * * * * * Features Low Power Consumption: 25uATyp.
