Product Change Notification
The NCV59744 is dual−rail very low dropout voltage regulator that is capable of providing an output current in excess of 3.0 A with a dropout voltage of 115 mV typ. at full load current. The devices are stable with ceramic and other low ESR output capacitors. This series contains adjustable output voltage version with output voltage down to 0.8 V. Internal protection features consist of built−in thermal shutdown and output current limiting protection. User−programmable Soft−Start and Power Good pins are available. The NCV59744 is available in QFN20−5x5−0.65P package.
