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 D 2 PAK
package.
