The LX8587A-33CDD is a special kind of voltage regulator, classified as a linear PMIC - Voltage Regulator. This voltage regulator is a low dropout type of voltage regulator, meaning it operates with a maximum input and output voltage differential as small as 1.3V when supplying a 3A current. This makes the LX8587A-33CDD ideal for supplying a lower voltage to a system, or preventing the voltage from being raised above a certain threshold to maintain system stability.

Application Field

The LX8587A-33CDD can be used in a variety of applications, ranging from telecom and power controllers, monitors and portable PCs, to current limited automotive audio and video systems. Other uses include supplying power to automotive drives, displays, and other current sensing and high power applications.

The LX8587A-33CDD can be used in fixed bias, linear, as well as non-linear applications. This makes it very versatile and allows for convenient integration into any system that requires a linear DC current-supply regulator.

Working Principle

The LX8587A-33CDD is a linear voltage regulator, meaning it regulates the output voltage by applying a drop across its internal pass transistors. The output voltage is determined by the input voltage and the output current through the control loop’s gain. As a result, the output voltage is inversely proportional to the current flowing through its pass transistors.

The LX8587A-33CDD is designed to supply a constant output voltage over a wide range of input voltages and current load. It works by sensing the input voltage at its input terminal, regulating the current flow through its pass transistor to achieve the desired output voltage, and maintaining that output voltage regardless of the input voltage or load current.

The LX8587A-33CDD also includes a protection circuit to enhance device reliability. This protection circuit prevents over-voltage, over-current, and over-temperature conditions, helping to protect the device’s components and enhance long term reliability.

Conclusion

The LX8587A-33CDD is a linear PMIC - Voltage Regulator designed for a variety of applications. It is a low dropout type of voltage regulator, meaning it operates with a maximum input and output voltage differential as low as 1.3V. It is designed to supply a constant output voltage over a wide range of input voltages and current load. The LX8587A-33CDD also includes a protection circuit to enhance device reliability and protect the device’s components.
