Working Principle of NCV85082BPD33R2G

The NCV85082BPD33R2G is a linear voltage regulator which uses an internal PMOS iron-based transter to control the output voltage. It includes a current-sense pass transistor and a feedback loop which coupled to the feedback pin provides fast response time and accurate regulation of the output voltage. This device has a built-in reverse current-protection circuit to protect against reverse current flow from the output to the input. The P-channel MOSFET is operated to limit the output voltage by increasing or decreasing the voltage across the feedback network.

The NCV85082BPD33R2G also utilizes a charge-pump architecture for low noise and improved transient response. The charge pump provides active voltage regulation, reducing output voltage noise. In addition, the device also has a wideband error amplifier to reduce the output voltage noise and improve the load and line transient performance. The device also includes slew rate limiting, over-temperature protection, and soft-start circuitry to ensure reliable operation in any condition.
