Data Sheet

EC48117

The EC48117 is aseries of low dropout three-terminal

regulators with a dropout of 1.15V at 1A output cur-

rent.

The EC48117 series provides current limiting and ther-

mal shutdown. Its circuit includes a trimmed bandgap

reference to assure output voltage accuracy to be

within 1%. Current limit is trimmed to ensure specified

output current and controlled short-circuit current. On-

chip thermal shutdown provides protection against any

combination of overload and ambient temperature that

would create excessive junction temperature.

The EC48117 has an adjustable version that can pro-

vide the output voltage from 1.25V to 12V with only 2

external resistors.

The EC48117 series is available in the industry standard

SOT-223, SOT-89, TO-220, TO-252,TO-263

power packages.
