Technology Description
400mA LDO Dropout Voltage Regulator
ACE555 is a series of low dropout three terminal regulators with a dropout of 1.22V at 400mA load current. Other than a fixed version（Vout＝1.8V,2.5V,2.85V,3.3V,5V）, ACE555 has an adjustable version, which can provide an output voltage from 1.25 to 13.8V with only two external resistors. ACE555 offers thermal shut down and current limit functions, to assure the stability of chip and power system. And it uses trimming technique to guarantee output voltage accuracy within ±2％. ACE555 is available in SOT-89-3 power Package. Lead free package is also available on command.
Features
Other than a fixed version and an adjustable version, output value can be customized on command. Maximum output current is 400mA Output voltage accuracy is within ±1％ Range of operation input voltage: Max 18V Line regulation: 0.2％ Load regulation: 0.4％ Environment Temperature: -50℃~140℃
