Overview
The NCV59748MLADJTBG is a dual-rail very low dropout voltage regulator produced by onsemi. This device is capable of providing an output current in excess of 1.5 A with a dropout voltage of 60 mV typical at full load current. It is stable with ceramic and any other type of output capacitor greater than or equal to 2.2 µF. The NCV59748 series includes adjustable output voltage versions with output voltages down to 0.8 V and a fixed voltage version of 0.75 V. The regulator features internal protection including built-in thermal shutdown and output current limiting protection. Additionally, it offers user-programmable Soft-Start and Power-Good pins. The device is packaged in a DFN10 3×3 package with wettable flank options available for Enhanced Optical Inspection.
