Working Principle of LP2981-28DBVTE4

The LP2981-28DBVTE4 works using Linear Voltage Regulation (LVR). This works by having an input voltage that is provided to the LP2981-28DBVTE4 which is then regulated and outputted. The LVR circuit is composed of a p-channel type field effect transistor that is connected in series with a voltage control transistor, and a current-limiting resistor. The voltage control transistor, also known as a reference voltage, helps to keep the output voltage at a constant level. Furthermore, the current-limiting resistor allows the circuit to limit the current flowing through the circuit. This helps to reduce the load and helps a system to operate more efficiently.
