Maxim Integrated MAX8878AUK28-T Voltage Regulator

The MAX8878AUK28-T from Maxim Integrated is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver a well-regulated power supply for portable and space-constrained electronics. This precision voltage regulator is capable of sourcing up to 150mA of output current while maintaining a low 160μA of quiescent current, making it an ideal solution for battery-operated devices where power efficiency is critical.

With a fixed output voltage of 2.8V, the MAX8878AUK28-T ensures a stable voltage supply for sensitive components such as microprocessors, memory, and analog circuits. The device features a tight output accuracy of ±1.5%, which helps maintain system reliability and performance even under varying load and input conditions.

The regulator's low dropout voltage, typically just 120mV at 150mA load, allows for efficient operation even when the input voltage is close to the output voltage, thus extending battery life in portable applications. Additionally, the MAX8878AUK28-T is equipped with a range of protective features, including thermal overload protection, short-circuit protection, and a reverse battery protection circuit, which safeguards the device and the load from potential damage.

Enclosed in a compact SOT-23 package, the MAX8878AUK28-T is designed for space-saving on PCBs, making it an excellent choice for mobile phones, PDAs, and other handheld devices. Its low external component count requirement simplifies design and reduces overall system cost.

The MAX8878AUK28-T also offers a fast transient response, which is essential for applications that experience rapid changes in load, such as powering CPU cores. This ensures that the output voltage remains stable without significant deviation, which is crucial for maintaining the performance of the powered device.

In summary, the Maxim Integrated MAX8878AUK28-T is a robust and reliable voltage regulator that combines high efficiency, precise voltage control, and a comprehensive set of protection features in a miniature package suitable for a wide range of applications.
