The MAX5086AATE+T is a linear voltage regulator designed to provide a simple and efficient power management solution. It features a range of adjustable output voltages, ranging from 0.8V to 5.5V, with a minimum 5% accuracy over temperature, and the ability to deliver up to 2.5A. The device also includes a wide variety of features including output enable control, over-temperature protection, and short-circuit protection.

The MAX5086AATE+T is ideally suited for use in applications such as smart phones, tablet PCs, and digital cameras, which require a high level of accuracy, high efficiency, and low noise. In addition, the device is able to meet the high-end performance requirements set by the higher-end applications such as network infrastructure, digital signage, and automotive electronics.

The working principle of the MAX5086AATE+T is based on the concept of the fixed output voltage, adjustable output voltage, and wide input range (WIR). It utilizes a combination of controlled power dissipation and voltage regulation techniques to maintain a stable output voltage when subjected to input voltage variations, line noise, and load transients. The output voltage is set by an external resistor network, which is connected to an external series of pins with an accurate 0.1V/step range. The combination of the pinned connection and the internal voltage reference creates a temperature-stable output voltage.

The output voltage is controlled by the pulse-width modulated (PWM) control circuitry and a variable duty-cycle to maintain a stable output voltage. The PWM control has a fast response time to line voltage fluctuations, and enables the device to respond quickly to load transients, allowing it to deliver high efficiency and low noise operation. The high efficiency of the device is also attributed to its low quiescent current consumption, allowing it to minimize power consumption and reduce power dissipation.

In addition to providing a stable output voltage and good efficiency, the MAX5086AATE+T also includes protection features to protect the device from overloads, short circuits and overheating. The over-temperature protection feature protects the device from excessive temperature, while the device’s out-of-regulation feature turns off the output voltage until the temperature returns to a normal range. The device also features an output enable control pin, which can be used to disable the output when not in use and provide additional protection against over-voltage conditions. This output enable pin is active low, meaning it must be left unconnected or pulled to ground to activate the output.

The MAX5086AATE+T is the ideal solution for a variety of applications where a high performance, highly efficient, and low-noise voltage regulator is required. With its advanced protection features, adjustable output voltage and wide input range, it offers a simple and efficient solution for power management requirements.
