XRP6274 Datasheet | Exar

DESCRIPTION The XRP6274 is an ultra low dropout voltage regulator capable of delivering 2A output currents. It is unique in the industry in being able to operate from a single supply rail of 1.045V to 2.625V without the need for a noise generating charge pump. With its ultra low dropout voltage of 140m V at full load guaranteed over temperature, the XRP6274 achieves conversions previously unavailable. The output voltage can be set as low as 0.6V with ±0.5% accuracy making the XRP6274 perfectly suited for powering low voltage devices such as FPGAs, DSPs, ASICs, and other SOCs. Built-in current limit, reverse bias and thermal protection ensures safe operation under abnormal operating conditions. An enable function, soft start and Power Good flag plete the feature set. The XRP6274 is offered in Ro HS pliant, “green”/halogen free 10-pin 3x3mm DFN package.
