LT3080IT#PBF

LT3080IT#PBF Application Field and Working Principle

The LT3080IT#PBF is a high performance current-mode, low dropout (LDO) linear regulator with a wide operating voltage range of 2V to 10V. It is suitable for applications that require high efficiency and precise output voltage. It is designed to provide an output of between 5V to 10V (± 2.5%), and consumes an average current of only 60 nA.

The LT3080IT#PBF has an integrated -sense amplifier to reduce output voltages and provides a temperature compensated regulating voltage. The amplifier is designed to provide an output voltage range from 0V to 12V (± 2.5%), when operated from a 2V to 10V input. The power-on reset threshold is between 5V to 17V.

The LT3080IT#PBF includes a “self-correcting” feature that allows the output voltage to remain stable during varying input voltages. It provides a high accuracy of regulation of 0.1% over the entire 1.6V to 10V input voltage range. It also includes adjustable current limiting, overvoltage protection, an output enable pin, and over-temperature protection.

Working Principle

In linear regulation, the input voltage is connected directly to the output by a low-dropout response resistor. The output voltage is determined by the voltage drop across the resistor, which is proportional to the input current. The LT3080IT#PBF uses a low-dropout response regulator that maintains the output voltage when the input voltage is varied. The low-dropout voltage regulator is capable of maintaining the output voltage even when the input voltage is varied or dropped to as low as 1.5V.

The LT3080IT#PBF employs a “self-correcting” circuit that regulates the output voltage. This circuit monitors the output voltage and quickly compensates for any fluctuations caused by changes in the input voltage. This allows the output voltage to remain stable, even when input voltage is varied in a wide range.

Applications Fields

The LT3080IT#PBF is an ideal choice for applications that require high accuracy and low distortion operation over a wide range of input voltages. It is particularly useful in high reliability systems such as medical electronics, renewable energy, industrial, automotive and telecom applications.

The LT3080IT#PBF is also suitable for portable, low-noise and low-power applications. It is designed to provide excellent regulation performance and low output noise of 45nV/rtHz. It is also capable of providing a fast transient response, ensuring that the output voltage remains stable over varying input voltages.

A few common applications for the LT3080IT#PBF include powering router and wireless systems, 12V to 5V regulator circuits, gaming systems, alarm systems and security cameras. The LT3080IT#PBF also can be used for automotive, avionics and military systems. It is also suitable for low-noise and low-power applications.

Conclusion

The LT3080IT#PBF is a high accuracy, low dropout linear voltage regulator with a wide operating voltage range and precision output. It includes self-correcting circuitry to maintain a stable output voltage. It also features adjustable current-limiting and over-temperature protection. The LT3080IT#PBF is suitable for a wide range of applications, including medical electronics, automobile systems, avionics and military systems.
