The LE80ABD is a 3-terminal voltage regulator that provides an output voltage of up to 50V and a maximum current of 2A. It has a quiescent output current of up to 20mV. The device features low-noise operation, fast transient response, and wide temperature range operation, making it suitable for a variety of applications. It also has an adjustable temperature range for optimal operation. Additionally, it offers a broad input voltage range and enhanced protection features.

Benefits

The LE80ABD voltage regulator offers several benefits for applications requiring a regulated power supply. It has a low quiescent current and fast transient response, making it suitable for applications requiring efficient power conversion and fast response times. Its wide input voltage range ensures that the voltage regulator will work with most power sources. Additionally, it has an adjustable temperature range, allowing the user to adjust the device to best suit their application. The integrated protection features protect against short circuits and over temperature conditions, providing increased safety and reliability.

Operating Principle

The LE80ABD voltage regulator operates by means of a feedback loop. The input voltage is applied to the input terminals of the regulator and the current that is flowing through the internal components of the regulator is monitored. The regulator then compares the measured current to a desired set-point, and adjusts the output voltage as necessary in order to maintain the correct current. As the input voltage fluctuates, the regulator automatically adjusts the output voltage to ensure a stable power delivery. This ensures that the output voltage remains steady and reliable, even in the most challenging of environments.

Applications

The LE80ABD voltage regulator can be used a variety of applications, including automotive, industrial, and medical applications. In automotive applications, it can be used to regulate the power supply of electronic modules or components, preventing them from over- or under-heating. In industrial applications, it can be used to control the output voltage of an AC power supply, ensuring that the power delivered is consistent and reliable. In medical applications, it can be used to regulate the power supply of medical devices, allowing them to run safely and efficiently.

Conclusion

The LE80ABD voltage regulator is a low-cost, high-performance regulator suitable for a variety of applications. It features a broad input voltage range, low noise operation, fast transient response, adjustable temperature range, and enhanced protection features. All of these features make the LE80ABD an ideal choice for a wide range of applications, including automotive, industrial, and medical applications.
