Overview
The NCV59748MNADJTBG is a dual-rail very low dropout (LDO) linear 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 regulator features adjustable output voltage versions with output voltages down to 0.8 V and includes a 0.75 V fixed voltage version. It is packaged in a DFN10 3×3 package with wettable flank options for enhanced optical inspection.
