REG103FA-2.5/500G3 Application Field and Working Principle

REG103FA-2.5/500G3 is a linear voltage regulator, specifically designed to supply the power needs of industrial, medical, and consumer equipment. This highly efficient, yet low power consumption regulator is made with a single, low-frequency current output that is capable of regulating input voltage levels down to 3V. This product series is available in a wide range of fixed output voltages and output current levels, and can be used for various applications such as system voltage regulation and thermal management.

Working Principle

The REG103FA-2.5/500G3 works through linear regulation, which is the process of regulating input voltage levels to a predetermined value provided by the user. This is achieved by comparing the nominal value of the desired output voltage with the actual input voltage. When the input voltage is higher than the desired output voltage, the regulator reduces its output current to bring the output voltage down. On the other hand, if the input voltage is lower than the desired output voltage, the regulator increases its output current to boost the output voltage up.

Operation

The REG103FA-2.5/500G3 is able to maintain output stability when used in environments with varying input voltages. This is achieved by the internal soft-start feature, which allows the device to make gradual adjustments in order to maintain output voltage when the input voltage levels change. The device also features overvoltage protection, which ensures that the regulator’s output voltage remains within the predetermined range regardless of the input voltage levels.

Features

The REG103FA-2.5/500G3 is designed with a variety of features that make it an ideal power source for many industrial, medical and consumer applications. These include:-Low quiescent current, ranging from 10~50 uA-High efficiency, up to 93%-Low dropout voltage, ranging from 0.2 to 1.2V-Output power range from 0.5 to 5W-Wide range of fixed output voltages, ranging from 1.5V to 24V-Wide range of temperature operation, from -40°C to +85°C-Wide environmental protection, meeting the highest environmental testing standardsThese features make the REG103FA-2.5/500G3 ideal for use in a variety of applications that require a reliable, efficient and low-power source of power.
