The LX8117B-00CST is a linear voltage regulator made by SemiWell, often used in power management applications. This voltage regulator provides efficient regulation of 5V or 3.3V output voltage from a wide 4.5V to 28V input range and operates at up to 4A of output current. It also has a short circuit protection and thermal shut down function. It has a low standby current of only 2uA and a low dropout operation of 0.2V to ensure maximum power efficiency. In addition, the LX8117B-00CST is compatible with a variety of capacitors, including tantalum, ceramic and aluminum electrolytic.

The LX8117B-00CST has a wide variety of applications, ranging from powering microcontrollers to providing regulated power supply to audio amplifiers. It is typically used in automotive and industrial applications such as wireless charging bays, fuel cells, and power supplies. The LX8117B-00CST is also used to provide precision current and voltage monitor in various systems.

The LX8117B-00CST has a simple linear voltage regulation. It has an internal PNP transistor that provides current regulation. This PNP transistor is connected in series between the input voltage and the output voltage. The current of this PNP transistor is controlled by the differential voltage across a special current sensing resistor. As the output current increases, the PNP transistor is driven harder to control the output voltage. This control method is simple and efficient and can provide stable voltage regulation.

The LX8117B-00CST is designed with high performance features including a fast transient response, low dropout operation, and low EMI. It has a low output voltage noise of 1uVrms and a fast start-up time of 8mSec. The LX8117B-00CST has a wide operating temperature range from -40 °C to 125 °C and has a high temperature stability of ±2.4 mV/°C. It also has low quiescent current of only 2uA. All these features make the LX8117B-00CST suitable for a wide range of power management applications.

The LX8117B-00CST is an ideal choice for powering microcontrollers, audio amplifiers, automotive, and industrial applications. It is reliable, efficient, and can provide stable voltage regulation with low power dissipation. With its high performance features, the LX8117B-00CST is well suited for applications where reliability and power efficiency are critical.
