NCP59744  
3.0 A, Dual-Rail Very  
Low-Dropout Linear  
Regulator with  
Programmable Soft-Start  
www.onsemi.com  
The NCP59744 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 95 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 NCP59744 is  
offered in DFN10 3x3 and QFN20 5x5 packages.
