Working Principle

The MIC2920A-4.8BT is a linear voltage regulator. It is designed to take an input voltage of up to 5.5V and regulate it down to 4.8V. The output voltage is maintained at a constant level by taking the difference between the input voltage and the output voltage and dissipating it as heat. This is achieved through the use of a built-in error amplifier and a MOSFET pass element.

The error amplifier is used to compare the output voltage with a reference voltage, and generates an output voltage proportional to the difference. This output voltage is then used to control the current flowing through the pass element, which in turn regulates the output voltage. This feedback loop ensures that the regulated output voltage is maintained regardless of changes in the input voltage.

The MIC2920A-4.8BT also offers several other features which make it an ideal low-drop linear voltage regulator. These features include: Low quiescent current, over-voltage protection, thermal shutdown and current limit.

The mic2920A-4.8BT is an ideal choice for a wide range of applications requiring low-voltage regulation, such as those outlined above. Its combination of features and advantages make it simple to use and highly reliable.
