Low Voltage Power Supplies

Robert Dobkin - Chief Technical Officer Jun 9th 2016
In this video, Linear Technology Co-founder and CTO Bob Dobkin discusses low voltage power supplies less than half a volt. Most of today's power supplies have a reference of 0.6 volts, which means the output voltage must be greater than 0.6 volts. Several years ago, Linear Technology pioneered a new type of current source reference ...
