Introduction
A new regulator architecture the LTC3600 (first introduced with the LT3080 linear regulator) has wider output range and better regulation than traditional regulators. Using a precision 50μA current source and a voltage follower, the output is adjustable from “0V” to close to VIN. Normally, the lowest output voltage is limited to the reference voltage. However, this new regulator has a ...
