Working Principle

The TL1963A-18DCQT is a low-noise low-dropout linear regulator that operates by controlling the current that flows through the pass transistor. When the input voltage is high enough, the regulator reduces the current flowing through the pass transistor, thus maintaining the output voltage. As the input voltage drops, the current increases to maintain the output voltage. The output voltage can be adjusted by connecting an adjustable external resistive divider.
