Working Principles
The BD49L42G-TL is a linear voltage regulator that utilizes 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 stable output voltage. When the input voltage exceeds the desired output voltage, the pass transistor reduces its resistance, allowing excess voltage to bypass it. Conversely, when the input voltage drops below the desired output voltage, the pass transistor increases its resistance, compensating for the voltage difference.
