NCP631

NCP631 3.0 A Linear Voltage Regulator with Soft−Start The NCP631 is a low dropout positive voltage regulator that is capable of providing a guaranteed output current of 3.0 A with a maximum dropout voltage of 1.25 V at 3.0 A over temperature. The NCP631 is currently offered as a fixed voltage version at 3.47 V. On chip trimming adjusts the reference/output voltage to within "1.5% accuracy. The Soft−Start function allows control of start up times. This prevents current spikes at start up due to output capacitor in−rush current. Internal protection features consist of output foldback current limiting, and thermal shutdown. The NCP631 is available in D2PAK package.
