The NCP5663 is a high performance, low dropout linear regulator designed for high power applications that require up to 3.0 A current. It is offered in both fixed and adjustable output versions. With output voltages as low as 0.9 V and ultra−fast response times for load transients, the NCP5663 also provides additional features such as Enable and Error Flag (for the fixed output version), increasing the utility of this device. A thermally robust, 5 pin D2Pak, combined with an architecture that offers low ground current (independent of load), provides for a superior high−current LDO solution.
