Voltage Regulator Module
Voltage Regulator Module
Describe the limitations of using an LDO regulator during low battery conditions such as Crank.?
Explain how to calculate the minimum operating voltage of the module to prevent a MCU reset. What can be done to increase the time before reset and comment on the benefits/drawbacks of each?
This sounds like part of a question out of some textbook. There is additional information that you have not provided to us, that is essential to analyzing this question.
I say this because you do not tell us anything about the "module" you reference. The minimum operating voltage of the LDO regulator and the methods that would forestall the reset of the MCU would be dependent upon how the module was constructed.
