Working Principles

The MIC5514-3.3YMT-TR is a linear voltage regulator that operates by comparing the output voltage to a reference voltage. It adjusts the resistance between the input and output to maintain a stable output voltage, even when the input voltage fluctuates.

When the input voltage exceeds the desired output voltage, the regulator reduces the resistance to lower the output voltage. Conversely, if the input voltage drops below the desired output voltage, the regulator increases the resistance to raise the output voltage.
