XR71211
XR71211 is 1.5A Ultra Low Dropout Voltage Regulator manufactured by Exar.
1.5A Ultra Low Dropout Voltage Regulator
General Description
The XR71211 is an ultra low dropout voltage regulator capable of delivering an output of 1.5Amps. It differentiates from its petitors 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 250m V 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 plete the feature set. Built-in current limit, reverse bias and thermal protection ensures safe operation under abnormal operating conditions.
The XR71211 is offered in Ro HS pliant, “green”/halogen free 10-pin 3x3mm DFN package.
