LX8385-33IDD

The LX8385-33IDD is a low-dropout linear voltage regulator, designed for applications that require stable, low noise, low voltage output. It is designed to provide up to 1A of output current with a supply voltage of 0.4V to 5.5V, and has an adjustable output voltage range of -0.3V to 5.9V. It can be used for a variety of applications, including microcontrollers, portable devices, consumer electronics, and industrial controls.

The LX8385-33IDD is based on an innovative voltage-tracking architecture with a fast transient response. It features adjustable output voltage, ultra-low power consumption, and low output noise. It also features EMI filtering, thermal overload protection, and current limiting. The output voltage is adjustable with a simple external voltage divider. Additionally, the device can be put into a low current sleep mode for power savings.

The working principle of the LX8385-33IDD is simple but important. It monitors the voltage supplied to its input and tries to keep the output voltage stable. When the input voltage is higher than the output voltage, the differential voltage across the regulator is zero, and the regulator turns off. When the input voltage is lower than the output voltage, the regulator turns on and the current input to the output is equal to the load current on the output minus the quiescent current of the regulator. The regulator then moves the output voltage closer to the input voltage, until the difference is equal to the linear dropout voltage.

The device also includes an internal voltage-tracks architecture, which helps to reduce output noise, making it suitable for high-end applications. Additionally, it has built-in EMI-filtering, thermal overload protection, and current limiting circuitry. The EMI filtering helps to minimize the amount of interference that the device produces, and the thermal overload protection prevents the device from operating in an unsafe condition, ensuring safety and protection for your devices.

The LX8385-33IDD is an excellent choice for applications that require a low-dropout linear voltage regulator with an adjustable output voltage range, low noise, and low power consumption. It is designed for use in a wide range of applications, including microcontrollers, portable devices, consumer electronics, and industrial controls.
