Working Principles

The MIC708RM is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the reference voltage with a fraction of the output voltage through a feedback network. The pass transistor adjusts its resistance to maintain a constant output voltage despite changes in input voltage or load conditions. This ensures a stable and regulated output voltage for the connected load.
