I am looking at MAX883 voltage regulator and from the documentation is not very clear whats the difference.
It says this about pin OFF:
In this mode, the pass transistor, control circuit, reference, and all biases are turned off
And this is writen about STBY:
feature that disconnectsthe input from the output when STBY is brought low, but keeps all other circuitry awake. In this mode, V_OUT drops to 0, and the internal biasing circuitry (including the low-battery comparator) remains on.
I understand that there are different elements of the regulator shut down, but I don't understand if the OFF would actualy turn "too much things off" in my usecase:
Using battery (4xAAA for testing for now) for power supply for membrane which is strictly operating on 3V +-0.1V. Therefore I need to hold the voltage at about 3V and when the egulator starts to drop under 2.9V it needs to be shut down to prevent any damage.
