I'm planning to use this LDO namely LT1085CT-5 and couldn't figure out the minimum input voltage.
The datasheet says "Operates Down to 1V Dropout" and the LT1085CT-5 means 5V fixed output. So does that mean a 5.9V output will not work or it just means to obtain 5V the minimum input should be 6V?
My aim is to obtain a regulated output(anything between 4.5V to 5.5V) from a 5.9V input.
The detailed datasheet given here. I was planning to use a 5.9V adapter as input voltage to this regulator and obtain a regulated voltage anything between 4.5V to 5.5V.
Would 5.9V have enough headroom for this regulator to obtain a regulated voltage(anything between(4.5V to 5.5V) or should I use an adjustable version?
