Working Principle

The LK112M32TR operates on a conventional linear regulator principle. It consists of three main components: an output voltage regulator, an error amplifier, and a pass transistor.The output voltage regulator compares the voltage at the output with a reference voltage (usually 2.5V) and adjusts the output voltage accordingly, if necessary. The error amplifier is used to compare the output voltage with the reference voltage, and adjusts the pass transistor as necessary. The current in the pass transistor is then adjusted according to the difference between the two voltages.The output voltage is then regulated according to the value of the external voltage source and the current in the pass transistor. This mechanism ensures that the regulated output voltage is maintained at the desired value, even under changing load conditions.
