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
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 D

PAK
package.
