The LX8585-33CDD is a linear voltage regulator for applications within the PMIC (Power Management Integrated Circuit) family. This regulator is designed to provide a stable, low noise supply voltage from either a DC voltage or from a weak or variable AC source. It can be used in a variety of applications, including low-voltage generators, multiple supply voltages voltage references, and precision current sources.

The LX8585-33CDD is a positive linear voltage regulator that has an adjustable output range of 1.25V to 33V. The maximum input and output currents are 1A and 0.5A respectively. The device is equipped with an internal current limit and thermal shutdown protection. The operating temperature range is -40 deg C to +85 deg C.

The working principle of this linear voltage regulator is simple. It uses a reference voltage, usually generated by a Zener diode, to regulate the output voltage to a specified level. The reference voltage is divided by two resistors which creates a voltage divider which sets the voltage on the "Adjust" or "Trim" pin. This allows the output voltage to be adjusted by changing the trim pin resistance. The reference voltage is compared to the output voltage, and if the output voltage is higher than the reference voltage, it is reduced by a series of pass elements, with the third stage being the one controlled by the trim pin. The regulator then works to maintain the output voltage at a pre-set level.

The LX8585-33CDD Linear Voltage Regulator offers high performance and low cost while providing a wide range of voltages and plenty of protection features. It is especially suitable for various types of electronic equipment, including electronic TVs, monitors, personal computers, cell phones, stereos, and other household appliances. This linear voltage regulator is designed to offer high levels of reliability, durability and flexibility in a package that is extremely cost-effective.
