Application Field

The REG1117A-2.5G4 has been designed to be used in a variety of applications that require a highly stable output voltage source. This includes low current portable electronics, instrumentation, and low power microcontrollers. The device is also suitable for use with other high power products, such as LED drivers, as it can provide a highly stable output voltage.

The device is also ideal for use as an adjustable power supply for applications that require low voltage and low current operation. The device can also be used for applications in automotive, industrial, and communication systems.

Working Principle

The REG1117A-2.5G4 is a linear voltage regulator, which means that it regulates the voltage by converting the input voltage and then outputting the stable voltage. It uses a feedback loop to constantly measure the output voltage and adjust the output voltage as necessary.

The device works by using an operational amplifier as a voltage comparator. The operational amplifier will compare the external reference voltage to the output of the regulator and, if the output voltage is different than the reference voltage, the operational amplifier will adjust the output of the regulator accordingly. In addition, the device also has current limit and thermal limit circuits to prevent the device from being over-driven or becoming too hot.

The REG1117A-2.5G4 is a highly efficient and reliable linear voltage regulator. The device is also small and lightweight, making it ideal for use in tight spaces and portable applications. The device’s low voltage drop and low output current makes it suitable for powering a variety of low power applications.
