Introduction

The ILC7083AIM5285X (MMV7805) is a three-terminal linear voltage regulator designed for use in various industrial, automotive, and consumer electronic applications. The MMV7805 is a low-dropout (LDO) regulator that is capable of providing load current of up to 5A and output voltage options ranging from 1.2V to 5.1V, with adjustable voltage options that range from 0.8V up to 5.1V.

Features and Benefits

The MMV7805 has many advantages over traditional linear voltage regulators, such as lower cost and better transient response, thermal stability, low noise, and higher efficiency. The MMV7805 features over-temperature protection (OTP) to protect the device and load from potential damage due to long-term temperature excursions by limiting the output voltage. Additionally, the MMV7805 features over-current protection (OCP) to protect the device and load from potential damage due to high current conditions by limiting the output current. The MMV7805 offers excellent transient response, allowing the device to quickly recover from load transients and maintain a steady-state output voltage. The device offers low output noise and improved ripple rejection for noise-sensitive applications. The high PSRR of the MMV7805 makes it ideal for high-noise applications, as it can reject input noise from sources such as power-supply switching and cellular signals.The MMV7805 is ideal for use in mobile phones, MP3 players, game consoles, and other portable electronic devices. The device is built with lead-free technology for compliance with the RoHS directive. The device is also packaged in an ultra-small 3x3mm QFN package for improved thermal performance and easy PCB integration.

Working Principle

The MMV7805 is a three-terminal linear voltage regulator. The device consists of an integral voltage reference, error amplifier, control logic, output buffer and main switch. The input voltage is applied to the left terminal and the output voltage is regulated by the controlled conduction of the main switch.The MMV7805 starts regulation when the input voltage is above the operating range, which is typically about 0.8V higher than the rated output voltage. The output voltage is regulated by adjusting the reference voltage, which is applied to the error amplifier. The error amplifier then compares the reference voltage with the voltage on the right terminal. The difference between the two voltages is referred to as the “error voltage”. The error amplifier then drives the control logic, which in turn drives the main switch. When the error voltage is above the regulation point, the main switch is driven in a conductive state, allowing current to flow from the input to the output and regulate the output voltage. When the error voltage is below the regulation point, the main switch is driven in a non-conductive state, causing the output voltage to drop.

Conclusion

The ILC7083AIM5285X (MMV7805) is a three-terminal linear voltage regulator designed for use in various industrial, automotive, and consumer electronic applications. The device offers low output noise and improved ripple rejection, along with over-temperature and over-current protection for reliable operation in noisy environments. The device is packaged in a 3x3mm QFN package for improved thermal performance and easy PCB integration. The MMV7805 is ideal for use in mobile phones, MP3 players, game consoles, and other portable electronic devices.
