Application Field and Working Principle

The LE45CZ voltage regulator is a feature rich and highly accurate device that can provide a constant voltage for all kinds of applications. It is commonly used in industrial automation, telecom, networking system, automotive, and other applications. This device works on the principle of voltage regulation or voltage reduction. It is a three-terminal adjustable voltage regulator that operates on the principle of supplying a fixed output voltage in response to an input signal.

This device works by sensing the voltage between its input and sense pins. This voltage is compared to an internally generated voltage reference. If the input voltage is higher than the reference voltage, the device reduces the output voltage. Conversely, if the input voltage is lower than the reference voltage, the device increases the output voltage. The output voltage is maintained constant by balancing the appropriate amount of current at the output.

Advantages

The LE45CZ voltage regulator offers several advantages. The first advantage is its low quiescent current, which allows for better efficiency and reduced power consumption. This is particularly important for battery powered applications, where low power consumption is essential. Secondly, the device has an excellent voltage accuracy, with an output accuracy of ±1.0%. This ensures that the output voltage always remains constant and does not fluctuate. Further, the device offers good voltage line and load regulation, which is beneficial for applications with varying loads. This helps to ensure constant output voltages even during sudden load changes. The device also has over current protection and circuit protection, which helps to prevent electrical overloading or circuit failure.

The LE45CZ voltage regulator is housed in an epoxy and glass coated SOP16 package. This ensures that the device is robust and resistant to environmental factors such as heat, moisture and vibration. The size of the package also makes the device ideal for small footprint applications, where physical space is a constraint. Additionally, the device is compatible with a wide range of input power supplies, including AC, DC and unregulated DC. This ensures compatibility with multiple external power sources.

In conclusion, the LE45CZ voltage regulator is an ideal choice for applications requiring constant voltage supply. It offers excellent features such as low quiescent current, high voltage accuracy, wide output voltage range, over current protection, circuit protection, and thermal protection. Furthermore, it is housed in an epoxy and glass coated SOP16 package, allowing it to accommodate small footprints. Finally, the device is compatible with a wide range of input power supplies, further enhancing its usability.
