The LP2985AIM5X-4.0 is a type of PMIC – Voltage Regulators – Linear, which is designed to provide an adjustable and efficient regulated output voltage. It is designed to simplify advanced voltage regulation and eliminates the need for an additional shunt references.

The LP2985AIM5X-4.0 is primarily used as a general-purpose voltage regulator, providing an adjustable and efficient output voltage. It can be used to supply small loads that require only a few watts of power and provides a low noise and low ripple output. The LP2985AIM5X-4.0 also includes a built-in voltage reference and current limiting circuit, which ensures the output voltage remains accurate, even in the presence of line or load transients or load changes . It also offers over-current and over-temperature protection, ensuring that the system remains reliable and safe for long-term use.

The LP2985AIM5X-4.0 is ideal for use in a wide range of applications, such as general-purpose voltage regulation, motor control, and supply systems. It can be used in applications where a high level of accuracy and low noise is desired, such as in Test and Measurement instruments, industrial controllers and precision circuitry. In addition, the LP2985AIM5X-4.0 is suitable for use in systems that need to operate in harsh environments, such as automotive and avionics systems.

The LP2985AIM5X-4.0 works by using a differential amplifier to sense the difference between the input voltage and the output voltage. The output voltage is then adjusted by a low noise error amplifier, which controls the output voltage of a P-channel MOSFET pass transistor. The amplifier reduces the voltage difference between the output and reference voltage until it reaches the target output voltage. The LP2985AIM5X-4.0 is capable of outputting up to 4A of load current, and has a typical input voltage range of 4.5 to 28V.

The LP2985AIM5X-4.0 also utilizes a unique alternating current/voltage mode of regulation, allowing for highly accurate load regulation even in the presence of heavy load steps and changes in line voltage. Additionally, the LP2985AIM5X-4.0 features a selectable fixed soft-start function to ensure that the output voltage remains stable during start up and end of life. The LP2985AIM5X-4.0 also features an integrated under-voltage lockout circuit that prevents the regulator from turning on until the input voltage reaches a predetermined level, ensuring a safe operating environment.

The LP2985AIM5X-4.0 is a highly efficient and reliable voltage regulator and is suitable for a wide range of applications. Its built-in features make it an ideal choice for a variety of system designs, offering high accuracy and low noise, as well as reliable protection for both the system and component. Its unique AC/DC mode of regulation and selectable soft-start feature makes it perfect for systems that require accurate and reliable voltage control.
