Application Field

LX8386B-00CDD is a step-down voltage regulator designed to provide an adjustable output voltage between 0.5V and 30V. It is well-suited for a wide variety of power management applications, including medical and industrial electronics, audio/video equipment, communications systems, and automotive electronics. The device is highly integrated and features a wide input voltage range of 8V ~ 30V. This allows it to be used in a variety of systems that have a limited power supply available. It has a fast transient response time, ensuring that the output voltage remains stable during load transients. Additionally, its fast current limiting capability prevents device damage from large overcurrents. It also has low dropout voltage, which enables it to continue to provide accurate regulation even when the input voltage is close to the output voltage.

Working Principle

LX8386B-00CDD is a linear voltage regulator. It works by converting the input voltage into an accurate, stable DC output voltage. The device consists of an internal voltage reference, an error amplifier, and an output driver stage. The voltage reference sets the output voltage by maintaining a constant voltage across a feedback voltage divider. The error amplifier compares the output voltage to the reference voltage and adjusts the output voltage to match the reference. The output driver stage amplifies the signal from the error amplifier and drives the output voltage accordingly. The device also features current limiting and thermal shutdown protection. The current limiting feature monitors the output current and cuts off the output voltage when it exceeds the maximum current limit. The thermal shutdown feature monitors the device temperature and shuts down the output voltage when the temperature reaches a predetermined limit. This protects the device from damage due to overloads and high temperatures.

Conclusion

LX8386B-00CDD is a high-quality, low-cost linear voltage regulator that is perfect for a wide range of power-management applications, including medical and industrial electronics, audio/video equipment, and communications systems. It has an adjustable output voltage range of 0.5V ~ 30V, a wide input voltage range of 8V ~ 30V, low dropout voltage, fast transient response time, high-efficiency current-limiting capability, and thermal shutdown protection. With its reliable performance and versatile features, LX8386B-00CDD is an ideal choice for various system power management requirements.
