APL1084

The APL1084 is a low dropout three-terminal adjust-able regulator with 5A output current capability.In order to obtain lower dropout voltage and faster transient response,which is critical for low voltage applications,the APL1084 has been optimized.The output available voltage range of adjustable version is from 1.25~5.75 with an input supply below 7V,and the fixed 3.3V output voltage device is also avaiable.Current limit is trimmed to ensure specified output current and controlled short-circuit current.On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures.

Features of the APL1084 are:(1)fast transient response; (2)guaranteed dropout voltage at multiple currents; (3)load regulation:0.05%typ.; (4)line dregulation:0.03%typ.; (5)low dropout voltage:1.3V typ.; (6)trimmed current limit:5V typ.; (7)on-chip thermal limiting:150 typ.; (8)standard 3-pin TO-220,TO252 and TO-263 power packages.

The absolute maximum ratings of the APL1084 can be summarized as:(1)input voltage:7V; (2)operating junction temperature range control section:0 to 125; (3)power transistor:0 to 125; (4)storage temperature range:-65 to 150; (5)lead temperature:260.If you want to know more information such as the electrical characteristics about the BF904, please download the datasheet in www.seekic.com or www.chinaicmart.com.
