The XR71211 is an ultra-low dropout voltage regulator capable of delivering an output of 1.5Amps. It is differentiated from its competitors by being able to operate from a single supply rail of 1.4V to 2.625V without the need for a noise generating charge pump or secondary bias rail.
This LDO provides a guaranteed dropout voltage of 250mV at maximum junction temperature and is ideal for 1.5V to 1.2V and 1.8V to 1.5V conversions. The output voltage can be set as low as 0.6V with +/-0.5% accuracy making the XR71211 perfectly suited for powering low voltage devices such as FPGAs, DSPs, ASICs and other SOCs.
An enable function, soft-start and power good flag complete the feature set. Built-in current limit, reverse bias and thermal protection ensure safe operation under abnormal operating conditions.
The XR71211 is offered in a RoHS compliant, green/halogen free 10-pin 3 x 3mm DFN package.
