Working Principles
The VRE3050BS 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 excess voltage is dissipated as heat, resulting in lower efficiency compared to switching regulators.
