XB1117P251FR-G

    The XB1117P251FR-G is a low dropout, adjustable output current limiting regulator with reverse current protection. It is developed by XYLINX Semiconductor and is part of their XB1117 family of products which is suitable for a wide range of voltage regulation applications.

    The XB1117P251FR-G is a Linear Voltage Regulator or LDO that provides an adjustable voltage output of between 0.8V and 4.7V. The output current is 2.5A maximum and it has a maximum dropout of 950mV at an operating temperature range of -40°C to +85°C. It has built-in reverse current protection and it is supplied in a small 8-pin package for efficient board space utilization.

    It is designed to convert low voltage input power sources such as batteries, up to 4.7V, into a regulated 5V or 3.3V output, depending on the wiring configuration. The XB1117P251FR-G can be used in a wide range of applications including consumer electronics, industrial electronics, data communications, and automotive electronics.

    The XB1117P251FR-G operates as a linear voltage regulator, meaning it regulates output voltage by dissipating excess energy from the output as heat. This regulation is accomplished by controlling the amount of current that is allowed to pass from the input to the output. This is done by comparing the actual output voltage with a voltage reference, then adjusting the amount of current that is allowed to pass.

    An advantage of using an LDO type voltage regulator is that it can provide a stable output voltage with a low-noise profile, thanks to its internal noise filtering and load regulation features. In addition, its low dropout voltage of 950mV allows it to operate at relatively low input voltage levels while still providing excellent stability and output current capability.

    The XB1117P251FR-G integrates current limiting protection, meaning that it will shut down if the output limit is exceeded. This can protect components connected to the output from overload damage as well as help to maximize the efficiency of the regulator by preventing it from operating at current levels outside of its designed operating range.

    In summary, the XB1117P251FR-G is a high performance adjustable voltage regulator with integrated current limiting protection and low dropout voltage. It is suitable for a wide range of applications which require regulated power from low voltage sources. Its low noise and current limiting features make it an ideal choice for noise-sensitive applications and extended battery life applications.
