NCP5661
Low Output Voltage,
UltraFast 1.0 A Low Dropout
Linear Regulator with Enable
The NCP5661 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 ultrafast 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, combined with
an architecture that offers low ground current (independent of load),
provides for a superior highcurrent LDO solution.
Features
