Overview
The NCP59744MN1ADJTBG, produced by onsemi, is a dual-rail very low dropout (LDO) voltage regulator. This device is capable of providing an output current in excess of 3.0 A with a dropout voltage of 75 mV typical at full load current. It features adjustable output voltage down to 0.8 V and is stable with ceramic and other low ESR output capacitors. The regulator includes internal protection features such as thermal shutdown and output current limiting, as well as user-programmable Soft-Start and Power Good pins. It is available in DFN10 3x3 and QFN20 5x5 packages, making it suitable for a variety of applications requiring high current and low dropout voltage.
