The RT9009GMS5 is a linear voltage regulator designed for applications requiring precision and low noise. It operates from an input voltage range of 2.25V to 5.5V and provides a regulated output rate of up to 5A. This linear voltage regulator integrates two MOSFETs, a driven control PWM, and two resistors to form a loop based control system. The two MOSFETs provide power coupling and the two resistors provide the current loop feedback to the PWMs.

The RT9009GMS5 has a wide range of features that make it suitable for applications including small form factor computing, laptop, and enterprise servers. It features excellent accuracy and fast transient response suitable for demanding applications. The device is a low-noise, high-side voltage regulator with an adjustable 2.5V to 5V output voltage range, providing a power supply up to 5A continuous current.

The on-chip control circuit of the RT9009GMS5 makes it an ideal choice for applications requiring minimal noise but demanding high accuracy and efficiency. It provides excellent transient response and high accuracy over its entire voltage range. Additionally, the on-chip linear regulator provides exceptional precision, typically 0.1% or better. There is also a built-in over-rail protection circuit that eliminates over-rail faults.

The RT9009GMS5 features a series of protection features including output enable control, over-current protection, over-temperature protection and EMI noise filtering. The over-temperature protection prevents thermal runaway when the internal temperature reaches a certain level. The over-current protection prevents current trips due to excessive load current. The output enable control prevents the output voltage from floating when the device is shut down, preserving the power source. The EMI noise filter prevents system noise from affecting the output voltage.

Moreover, the RT9009GMS5 integrates an optimized analog current limit control circuit and a short-circuit protection circuit that ensures reliable operation and greatly simplifies component selection. Its proprietary Constant Input/Output Resistance (CIRO) technology reduces output voltage drop, ensuring that the output voltage remains within the required voltage range.

In conclusion, the RT9009GMS5 is an excellent choice for applications requiring precision, noise reduction and good power efficiency. Its wide range of features, such as its EMI noise filter, over-rail protection, over-temperature protection, and Constant Input/Output Resistance (CIRO) technology make it an ideal choice for regulated voltage applications.
