XRP6275
3A Ultra Low Dropout Voltage Regulator
January 2015
GENERAL DESCRIPTION
The XRP6275 is an ultra low dropout voltage
regulator capable of delivering 3A 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 138mV at
full load guaranteed over temperature, the
XRP6275 achieves conversions previously
unavailable.
The output voltage can be set as low as 0.6V
with ±0.5% accuracy making the XRP6275
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
complete the feature set.
The XRP6275 is offered in RoHS compliant,
“green”/halogen free 10-pin 3x3mm DFN
package.
