Working Principle

NCP130AMX105TCG uses a linear voltage regulation technique to convert an input voltage to the desired output voltage. It uses a feedback loop to monitor the output voltage, and adjusts the output as necessary to maintain the set voltage. In this way, the device continuously maintains the desired output voltage, regardless of changes in input voltage or load conditions.

The device works by comparing the controlled node voltage with an internal reference voltage. The error signal that results from this comparison is then amplified and then used to adjust the output voltage. This adjustment is done by a current control loop, which includes a current mirror and a pass transistor. This regulation loop is termed a “constant current” or “proportional” regulator, and is the primary method of linear voltage regulation in the NCP130AMX105TCG.

In addition to maintaining the output voltage, the current control loop also controls the output current, thereby providing a level of current protection for the output load. This protection is implemented by limiting the output current when the voltage across the load approaches the regulated voltage.

Conclusion

The NCP130AMX105TCG is a highly-integrated linear voltage regulator (PMIC - Voltage Regulators - Linear) that blends tight regulation performance and power savings with long operating life and reliability. It is a popular choice for applications where precise and robust regulation performance is required over a wide range of conditions. Its high efficiency, low noise, and low no-load input current make this a desirable choice for many demanding applications.
