Description

The NCP5667 is a high performance, low dropout (LDO) linear voltage regulator designed for high power applications that require up to 3.0 A current. A thermally robust, 3 pin D2PAK, combined with an architecture that offers low ground current (independent of load), provides for a superior high-current LDO solution.
