Working Principle

The LDK130M15R uses a linear regulator to achieve a stable output voltage. It converts an input voltage and current into an output voltage and current by acting as a variable resistor. The current flowing through the resistor is regulated by a feedback loop which is generated by an internal error amplifier. This error amplifier compares the output voltage to a reference voltage and calculates the difference, or error. The error amplifier then adjusts the resistance of the regulator to compensate for the difference in output voltage. This results in a stable output voltage by using a linear regulator.
