The NCP5661/NCV5661 is a high performance, low dropout linear regulator designed for high power applications that require up to 1.0 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 NCP5661/NCV5661 also provides additional features such as Enable and Error Flag (for the fixed output version), increasing the utility of these devices. A thermally robust, 5 pin DPAK, combined with an architecture that offers low ground current (independent of load), provides for a superior high-current LDO solution.
