Features

The LX8585A-15CDD provides the following features for power management applications:• Low Dropout Voltage: Very low dropout voltage allows for the regulation of very low output voltages.• High Efficiency: Offers very high efficiency due to its low dropout voltage.• Low Shutdown Current: The device has a low shutdown current, making it ideal for battery operation.• Internal Current Limit: Internal over-current shutdown protection makes the device suitable for even the most demanding power management applications.• Over-Voltage Protection: The device has build-in over-voltage protection to protect against damage due to over-voltage conditions.

Application Field and Working Principle

The LX8585A-15CDD is designed to provide very low-dropout voltage regulation for a wide range of power management applications. The device can handle up to 3A or output current and is suited for both step-down and step-up applications.The device is a linear regulator, and works by controlling the output voltage through a voltage divider network. The feedback network is comprised of a resistor divider network, and is connected to the output voltage and to the reference voltage. The reference voltage is compared with the output voltage, and the error signal is fed back to the input. This feedback signal is amplified and used to adjust the output voltage of the device. The device then works to maintain the output voltage at a constant level. The LX8585A-15CDD also has built-in current limit protection, which helps protect against overloads. Over-voltage protection, which can shut down the outputs when an over-voltage condition is detected, is also included.

Conclusion

The LX8585A-15CDD is a low-dropout linear regulator designed for power management applications. It offers very high efficiency and low shutdown current, making it suitable for a wide range of applications. Its internal current limit and over-voltage protection features make it suitable for even the most demanding power management applications. The device can handle up to 3A of output current and is suited for both step-down and step-up applications.
