Linear Voltage Regulator, 3 A, Ultra-High PSRR

Favorite

Overview

The NCP630 is a low dropout (LDO) positive linear 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 within ? 1.5% accuracy. Internal protection features consist of output current limiting and thermal shutdown. NCP630 is available in D2PAK package.
