Abstract
A fully-integrated 5V-to-3.3V supply voltage regulator for application in digital ICs has been designed in a 3.3V 0.5µm CMOS process. The regulator is able to deliver peak current transients of 300mA while the output voltage remains within a margin of 10% around the nominal value. The circuit draws a static quiescent current of 1mA during normal operation and includes also a power-down mode with only 12µA current consumption. The die area is 1mm2and can be scaled proportional to the maximum peak current. Special precautions have been taken to allow 5V in the 3.3V process.
