Introduction

The LX8117-28CDD is a high-efficiency, low-dropout voltage regulator designed to provide a regulated output voltage and high power efficiency. It is a highly integrated, low-noise, high-speed linear regulator specifically designed to meet the requirements of consumer applications. This device provides excellent protection against voltage overshoots and reverse polarity, making it ideal for regulating voltage levels in consumer applications.

Application Field

The LX8117-28CDD is suitable for a wide range of consumer applications such as plug-and-play peripherals, consumer electronics, portable devices, and battery-powered equipment. It can also be used in automotive and industrial applications. The output voltage range is from 0.7V to 28V, making it an ideal choice for a variety of voltage regulation needs. It offers low noise, high efficiencies, and high current output, making it the perfect choice for consumer applications.

Working Principle

The core of the LX8117-28CDD is a ± 50mV wide-range, low-dropout linear regulator. The device operates off of a single-ended input voltage range of 0.7V to 5.5V and produces a regulated output voltage of up to 28V. The device is designed to drive high current loads up to 1.5A with an input capacitance of 2.5µF and an output capacitance of 10µF. The device is able to provide a wide voltage range and has a very high power efficiency of up to 95%.

To protect the device from short-circuit damage, it includes a thermal cut-off and a low quiescent current low voltage detector. The quiescent current low voltage detector monitors the voltage at the output and shuts down the regulator when the output voltage drops below the minimum programmed value. The thermal cut-off feature will shut down the regulator if the die temperature exceeds a preset level.

In addition to the safety features, the LX8117-28CDD also provides load-line protection. This feature ensures that the output voltage is stable under varying load conditions. This device also has a programmable slew-rate control to protect the device and the load during startup and fault conditions.

The LX8117-28CDD is designed with a low dropout voltage (LDO) regulator. This design provides improved efficiency over traditional linear regulators. The device is able to provide a regulated output with a dropout voltage as low as 100mV.

The LX8117-28CDD also includes an adjustable soft start feature that allows users to adjust the output voltage and reduce the inrush current. This feature prevents output voltage from overshooting when the device is plugged in, protecting it from current surge.

In conclusion, the LX8117-28CDD is a high-efficiency, low-dropout voltage regulator specifically designed for consumer applications. It provides excellent protection from voltage overshoots, reverse polarity, short-circuits, and over-currents. With its wide input voltage range and high current output, it is ideal for a variety of voltage regulation needs.
