Maxim Integrated MAX8579EUB+T Voltage Regulator

The MAX8579EUB+T from Maxim Integrated is a high-performance, low-dropout linear regulator designed to deliver a continuous 150mA output current. This component is housed in a compact, 10-pin µMAX package, making it an ideal choice for space-constrained applications. The MAX8579EUB+T operates over a wide input voltage range from 2.5V to 5.5V, making it suitable for a variety of power supply configurations, including single-cell lithium-ion (Li+) batteries, and fixed 3.3V or 5V power rails.

One of the key features of the MAX8579EUB+T is its low quiescent current, which is typically 90µA, enhancing its suitability for battery-powered and portable devices where power efficiency is crucial. Additionally, the device has a low dropout voltage of only 165mV at 150mA load, ensuring efficient operation even when the input-to-output voltage differential is minimal.

The MAX8579EUB+T offers a high level of precision with an output voltage accuracy of ±1.5%, ensuring reliable performance for sensitive electronic circuits. The regulator also includes an array of protection features such as short-circuit protection and thermal overload protection, safeguarding the device and the load from potential damage due to abnormal operating conditions.

Design flexibility is another advantage of the MAX8579EUB+T, as it provides the option to adjust the output voltage from 1.5V to 5V using external resistors. This adjustable output capability allows designers to tailor the regulator to meet the specific requirements of their application without the need for multiple different fixed-voltage regulators.

For applications requiring a fixed output voltage, the MAX8579 is also available in preset output voltage versions, eliminating the need for external feedback resistors and simplifying the design process. The device's enable (EN) input allows the output to be turned off, reducing the quiescent current to less than 1µA and further conserving battery life when the regulator is not in use.

In summary, the Maxim Integrated MAX8579EUB+T voltage regulator is a versatile, efficient, and reliable choice for a wide range of applications, from battery-operated devices to fixed-rail systems, where space is at a premium and energy efficiency is paramount.
