NCP59748  
1.5 A, Dual-Rail Very  
Low‐Dropout Linear  
Regulator with  
Programmable Soft‐Start  
www.onsemi.com  
The NCP59748 is dual−rail very low dropout voltage regulator,  
capable of providing an output current in excess of 1.5 A with a  
dropout voltage of 60 mV typ. at full load current. The devices are  
stable with ceramic and any other type of output capacitor 2.2 mF.  
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 on  
both QFN and DFN versions.
