LT3014HVEDD#PBF Application Field and Working Principle
The LT3014HVEDD#PBF belongs to the PMIC family of voltage regulators and is included under the linear sub-category. It is a very efficient, low quiescent current linear regulator with wide input voltage range, making it perfect for a variety of applications. This article discusses the application field and working principle of the LT3014HVEDD#PBF in detail.
Application Field
The LT3014HVEDD#PBF is ideally suited for use in low voltage and high current applications such as automotive, industrial, consumer, communication and portable devices. Its wide input voltage range allows it to operate from a variety of sources, including automotive battery (4V to 40V), solar panels, AC adapters and other sources. Its high efficiency and low quiescent current also make it an ideal choice for applications requiring minimal power consumption.
The high precision of the LT3014HVEDD#PBF is also a major asset, as it allows it to maintain tight regulation and deliver very accurate load voltages. This makes it extremely reliable and ideal for use in precision devices such as sensors, medical equipment and instrumentation that require precise voltage and current levels. The wide input and output voltage range, combined with the high efficiency, also make it a good choice for applications requiring buck or boost regulators, such as LED drivers.
Working Principle
The LT3014HVEDD#PBF operates on the linear regulator principle which uses a controlled amount of current passing through a cascaded series of transistors to regulate the output voltage. The LT3014HVEDD#PBF includes several components to ensure precise voltage and current regulation including:
- A precision voltage reference.
- A low power linear error amplifier.
- External current and temperature limiting.
- Robust and reliable power transistors.
- High-side and low-side MOSFET pass transistors.
The LT3014HVEDD#PBF regulates the input voltage by adjusting the current being passed through the cascaded transistors. As the voltage increases, more current is passed through the transistors, resulting in a higher output voltage. Conversely, when the voltage drops, less current is passed through the transistors, resulting in a lower output voltage. The active current control feature of the LT3014HVEDD#PBF also ensures precise current regulation over temperature and input voltage variations, resulting in a highly consistent output.
Conclusion
The LT3014HVEDD#PBF from Linear Technology is a highly efficient, low quiescent current linear regulator with wide input voltage range, making it perfect for a variety of applications. It is ideally suited for use in low voltage and high current applications such as automotive, industrial, consumer, communication and portable devices. Its high precision and wide input and output voltage range also make it a good choice for applications requiring buck or boost regulators. The LT3014HVEDD#PBF operates on the linear regulator principle which uses a controlled amount of current passing through a cascaded series of transistors to regulate the output voltage.
