LX8385B-33CDD, a linear voltage regulator, is widely applied in the power management and system power supply design. With the integrated dual-channel PWM and current-limiting protection feature, it can provide up to 33V of output voltage. LX8385B-33CDD is best suited for applications requiring highly stable and adjustable voltage output, such as notebook computers, storage systems and ATMs.

LX8385B-33CDD is a 3-terminal positive voltage regulator that regulates the output voltage to a constant value, which can be adjusted by changing the external resistor value. It consists of an internal semiconductor chip, any external power transistor, and three resistors. The transistor serves as an electronic switch that is turned on and off to control the voltage output. It is a variable voltage regulator, which means that the output voltage can be adjusted by varying the external resistor value.

The operating principle of LX8385B-33CDD is based on an adjustable voltage-controlled voltage regulator. In this type of regulator, the output voltage is determined by the voltage across a control pin, R1, which is connected to an internal reference voltage. The reference voltage is set by a resistor divider connected to the input voltage. The output voltage is then adjusted by adjusting the resistor divider ratio until the desired output voltage is achieved.

LX8385B-33CDD features a built-in complementary current limiting protection to protect the chip from over-current or short circuit. It also includes over-voltage protection (OVP) and over-temperature protection (OTP) features for safety. The device is built using surface mount technology, allowing for a smaller size and reduced power consumption.

LX8385B-33CDD is an ideal solution for applications requiring highly stable and adjustable voltage output. Its wide input voltage range and simple design make it well suited for applications such as notebook computers, storage systems, ATMS and other portable electronic devices. With the integrated dual-channel PWM and current-limiting protection feature, LX8385B-33CDD is sure to provide reliable operation and excellent voltage regulation performance.
