NCP5661_14 Datasheet, PDF (1/12 Pages) ON Semiconductor – Low Output Voltage Ultra-Fast 1.0 A Low Dropout Linear Regulator

NCP5661, NCV5661
Low Output Voltage,
Ultra-Fast 1.0 A Low Dropout
Linear Regulator with Enable
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
or DFN 3x3.3 mm, combined with an architecture that offers low
ground current (independent of load), provides for a superior
high−current LDO solution.
