The FAN2500S28X is a member of the Advanced Power Management (APM) family of Linear Voltage Regulators from Fairchild Semiconductor. It offers an adjustable output range from 0.8V to 28V with very high accuracy and low noise. The FAN2500S28X is also equipped with high power handling capability allowing higher output current than its competitors. Furthermore, it provides a free air die temperature up to 125°C, making it suitable for applications in harsh environments.

The FAN2500S28X is designed to provide higher current than other linear voltage regulators. It operates from an input voltage of 5V to 28V and delivers an accurate, low noise output. This device is capable of providing up to 3 A of continuous current and up to 5A of peak current, thus allowing it to easily handle high power requirements of applications. It is also capable of maintaining very tight output voltage regulation over a wide temperature range, making it an ideal solution for industrial and embedded application requirements.

The FAN2500S28X may be used for a variety of applications, including microcontrollers, DSPs, FPGAs, DC-DC converters, and other similar power management applications. For these applications, the FAN2500S28X provides very low noise output voltage with a very high level of accuracy. It also supports a variety of frequency bands, allowing it to be used in low power, high-frequency circuits.

At the heart of the FAN2500S28X is an output voltage control module which sets the output voltage. This module adjusts the output voltage based on an external reference voltage, usually an adjustable voltage source or a temperature sensor. The output voltage can also be externally adjusted without changing the input voltage. The output voltage is adjustable through an external resistor divider network and a trimming potentiometer. The output voltage is also adjustable using a digital interface.

The FAN2500S28X also provides external current limiting and over temperature protection. The over-temperature protection is useful for preventing the device from failing during overloads due to exceeding the maximum junction temperature. In addition, the FAN2500S28X also provides thermal shutdown, which triggers when the junction temperature reaches 150°C.

The FAN2500S28X meets industry standard footprints and comes in two versions for different output current requirements. It is available in a 24-pin small outline package (SOP) for higher current applications and a 28-pin flat lead plastic package (FLPP) for lower current applications. The device also features under-voltage lockout, which prevents operation when the input voltage is too low. This feature prevents accidental start-ups when, for example, the battery power has run out.

In conclusion, the FAN2500S28X is an efficient and reliable linear voltage regulator that is equipped with a number of features making it suitable for a variety of power management applications. It offers adjustable output range from 0.8V to 28V with high accuracy, low noise and high power handling capability. It also provides current limiting, over temperature protection and thermal shutdown for safety. The FAN2500S28X is available in two footprints, offering easy implementation in existing solutions.
