Working Principle

The REG104GA-5/2K5G4 is a linear voltage regulator based on a 3-terminal circuit topology. The voltage regulator uses a feedback loop to ensure that the output voltage remains constant despite any changes in input voltage or load. This feedback loop consists of an error amplifier, which compares the reference voltage to the output voltage, and adjusts the output voltage accordingly. The error amplifier is then used to generate a proportional output current, which is then used to control the output voltage.The REG104GA-5/2K5G4 also features current-foldback protection, which reduces the output current as the input voltage exceeds the maximum rating of the device. This reduces the risk of overcurrent and potential damage to the device.

Conclusion

The REG104GA-5/2K5G4 is a low dropout linear voltage regulator designed to maintain an extremely stable output voltage in the range of 5V to 24V. This voltage regulator is an ideal choice for applications requiring an accurate and reliable linear voltage regulator. Its features, such as low-input voltage noise, wide line and load regulation range, and high output current capabilities, make it suitable for a variety of applications. The voltage regulator is based on a 3-terminal circuit topology and current-foldback protection, which ensures stable and secure operation of the device.
