NCP5662, NCV5662
Low Output Voltage,
Ultra-Fast 2.0 A Low Dropout
Linear Regulator with Enable
The NCP5662/NCV5662 is a high performance, low dropout linear
regulator designed for high power applications that require up to 2.0 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 NCP5662/NCV5662 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
D PAK or DFN8 package, combined with an architecture that offers
low ground current (independent of load), provides for a superior
high-current LDO solution.
