LX8117A-33CDT is a 3A low drop-out (LDO) single linear voltage regulator integrated circuit. The device is capable of delivering up to 3A of continuous current, with an accuracy of 0.5%, over a wide input voltage range from 2.7V to 5.5V. It is designed to regulate all the voltage rails within a system, from 0.8V to 5.5V, ranging from higher current (>= 1.0A) to light load (<1mA) mode operation. It features a fast-transient-response (FTR) mode that gives excellent load-line performance for improved load and line transient response, as well as a low quiescent current. It is designed to work with a variety of input voltage and load capacity combinations, making it well suited for a wide range of applications.

LX8117A-33CDT is a low drop-out (LDO) linear voltage regulator. The device is a three-terminal regulator and can provide constant output voltage with an output current of up to 3A. It is ideal for applications that require high output current but have low voltage and limited space requirements, such as portable electronic devices, LED lighting, and industrial control systems. The LX8117A-33CDT is designed to provide excellent output accuracy and low dropout voltage over a wide input voltage and load current range.

The LX8117A-33CDT regulator provides a two-stage voltage regulation, as well as high accuracy and low noise in both stages. The first stage is controlled by a direct feed-forward compensation with an error amplifier, while the second stage is controlled by a high feedback ratio of current mode. In addition, the device utilizes a 1.0μA quiescent current with a low noise signal control, which allows the device to operate with a minimum number of external components.

The device has an adjustable output voltage, allowing the user to choose the desired output voltage between 0.8V and 5.5V. It also features brown-out protection and over-temperature protection. In addition, protection from short-circuit and over-voltage conditions can also be enabled by onboard, user-programmable FET switches.

LX8117A-33CDT is designed to provide reliable power regulation in various power system board designs, such as those used in PCs, mobile devices, embedded systems, and industrial equipment. It offers excellent power supply sequencing that can withstand inrush current spikes and eliminates the need for extra components such as a MOSFET to prevent damage to sensitive components. It is also a low-noise design and has very low output ripple.

In summary, LX8117A-33CDT is a 3A low drop-out linear voltage regulator designed to provide precision voltage regulation and beneficial features such as fast transient response, low quiescent current and high accuracy. Its two-stage regulation technology ensures accurate and efficient power supply regulation, giving users peace of mind that their equipment is protected against over-voltage and other power disruptions. It can be used in a wide range of applications, including PCs, mobile devices, embedded systems, and industrial equipment.
