Developedby Linear Technology, it provides a regulated output voltage of 18V and capable of supplying currents up to 1.5A.This low dropout voltage regulator was designed for a wide range of applications including automotive, industrial systems, medical equipment, processor systems, portable and communications equipment.

Application Field of MPQ 20056GG-18-P

The main application of MPQ 20056GG-18-P is in low noise and high accuracy voltage regulation. It is particularly used in automotive, industrial systems, medical equipment and processor systems. In addition, this voltage regulator is suitable for powering microprocessors, memory and other high current integrated circuits.

The over-current protection, short circuit protection and thermal shutdown make the MPQ 20056GG-18-P an ideal voltage regulator for use in even the most demanding applications. It is also suitable for use in battery-powered systems, as the low quiescent current of the regulator ensures a long battery life. The low output voltage regulation accuracy of just 0.3V also makes it an ideal regulator for low noise distortion applications.

Working Principle of MPQ 20056GG-18-P

The MPQ 20056GG-18-P is a three-pin, linear voltage regulator that operates by varying the amount of current flowing through the load. The output voltage is controlled by a feedback network comprising an input voltage source and a resistor, which provides a voltage reference. The regulator maintains the output voltage constant over its input voltage range of 2V to 28V by varying the amount of current flowing through the load.

The MPQ 20056GG-18-P has a very high output impedance, which helps to generate low noise voltages with no additional filtering components. The regulator can also support a resistive load that varies from 0Ω to 1 MΩ making it suitable for a wide range of applications. The low current draw of the MPQ 20056GG-18-P also helps to conserve power, making it suitable for battery-powered systems.

The MPQ 20056GG-18-P has a thermal shutdown protection that shuts down the regulator when the junction temperature exceeds 140°C. This prevents the regulator from burning out in cases of excessive current drawn due to a short circuit. The regulator also has an integrated protection against over-current and short-circuit conditions. It is also equipped with reverse battery and output overload protections.

In conclusion, the MPQ 20056GG-18-P is an ideal voltage regulator for use in precision and low noise distortion applications. Its high output impedance, low current draw, short-circuit and overload protection, and thermal shutdown make it a trusted choice for demanding applications.
