S-1721A2818-M6T1G

The S-1721A2818-M6T1G is a linear voltage regulator that is specifically designed to provide a wide range of voltage regulation, highly accurate regulation, low output noise and low input current to improve performance and extend battery life in modern devices. It is ideal for use in devices that require reliable power source delivery such as network-attached storage (NAS), digital signage, set-top boxes, Security Surveillance cameras and Point of Sale (POS) systems.

This voltage regulator is a part of the 1-A family of linear voltage regulators from S-1721. It is designed to provide 1-A of output current with an output voltage adjustable from 3.3 to 13.2V. It also has an ultra low dropout voltage of 300 mV, which allows it to provide a steady output even with varying input voltage levels. Additionally, it has programmable over voltage protection and thermal shutdown protection.

The S-1721A2818-M6T1G is a three-terminal regulator with an input voltage of 2.7V to 18V and an output voltage range of 2.7V to 13.2V. It features low quiescent current of 5 μA, fast response times and low output noise of typically 4 mVrms. The device will automatically shut down if the temperature rises above the absolute maximum rated temperature. This provides improved protection against short circuit, over-temperature and overload conditions.

The S-1721A2818-M6T1G is also equipped with a power-saving feature. It will automatically cycle the output voltage from OFF to ON and back OFF in order to maintain the desired output voltage without additional load current. This feature helps reduce energy consumption and improve the overall efficiency of the device.

The linear voltage regulator is manufactured using a high-performance CMOS process to ensure low-noise, high-efficiency operation. The process allows for low dissipation, improved self-heating control, and improved long-term stability. The device is rated to operate up to an ambient temperature of –40°C to 125°C.

The working principle of a linear voltage regulator is simple. The regulator takes a signal from an unregulated voltage source and puts it through a feedback loop consisting of an operational amplifier and voltage regulator. The operational amplifier uses the error between the output voltage and the reference voltage to control the magnitude of the output voltage by controlling the current that flows to the output. This process of error detection and regulation continues until the desired voltage is reached.

The S-1721A2818-M6T1G linear voltage regulator is designed for applications that require reliable power source delivery. It is designed to provide high efficiency, low noise, and low input current for improved performance and extended battery life. The regulator is also equipped with programmable overvoltage protection and thermal shutdown protection for added safety and reliability. Additionally, the power-saving feature helps reduce energy consumption and improve the overall efficiency of the device.
