Working Principle

In a linear voltage regulator, current is regulated from the power bus through a resistor. The current control loop consists of two elements: the voltage reference block and the error amplifier. The output of the error amplifier is proportional to the magnitude of the error. That is, it is the difference between the output voltage and the voltage reference. The output of the error amplifier is processed by the internal control logic to generate current control signals to switch the N-FET components. The current control loop also provides a negative feedback loop that drives the output voltage towards the set point. A protection control system is also integrated with the LDS3985M15R which makes sure that the system is operational and the protections of the load and power devices are not compromised.

Advantages

The LDS3985M15R linear voltage regulator has many advantages over conventional linear regulator designs.
