Overview
Bay Linear Inspire the Linear Power 300 mA CMOS Low Dropout LDO Description The B4300 series are a group of positive output voltage, three-pin regulators, which provide a high current even when the input/output voltage differential is small.
Low power consumption and high accuracy is achieved though CMOS and programmable fuse technologies.
