Description

General part information

NCP5661 Series

The NCP5661 is a high performance, low dropout (LDO) linear voltage 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 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 DPAK or DFN 3.0 x 3.3 mm, combined with an architecture that offers low ground current (independent of load), provides for a superior high-current LDO solution.
