NCP630
3.0 A Fast Linear Voltage
Regulators
The NCP630 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
fast turn on time allows step changes in loads commonly found in low
voltage microprocessor applications. The NCP630 is currently offered
as an adjustable output version that can be programmed down to 1.2 V
with two external resistors and as a fixed output version at 3.47 V. On
chip trimming adjusts the reference/output voltage to within
accuracy. Internal protection features consist of output current limiting
and thermal shutdown. NCP630 is available in D
2
PAK package.
