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 www.onsemi.com current. It is offered in both fixed and adjustable output versions. With MARKING output voltages as low as 0.9 V and ultrafast response times for load DIAGRAMS transients, the NCP5661/NCV5661 also provides additional features such as Enable and Error Flag (for the fixed output version), NCP5661 NCV5661 increasing the utility of these devices. A thermally robust, 5 pin DPAK or DFN 3x3.3 mm, combined with an architecture that offers low 1 5661xG V5661xG ground current (independent of load), provides for a superior 5 ALYWW ALYWW highcurrent LDO solution.
