Working Principles

The 70V05L15PFG8 is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the reference voltage with the feedback voltage, adjusting the pass transistor's resistance to maintain a constant output voltage. The dropout voltage is the minimum voltage difference required between the input and output for proper regulation.
