Maxim Integrated MAX8869EUE18 Low-Dropout Linear Regulator

The MAX8869EUE18 from Maxim Integrated is a high-performance, low-dropout (LDO) linear voltage regulator that delivers a fixed output of 1.8V with an input voltage range of 2.5V to 6.5V. This device is designed to provide up to 500mA of output current while maintaining excellent load and line regulation, making it an ideal choice for portable electronics, such as PDAs, mobile phones, and wireless devices.

One of the key features of the MAX8869EUE18 is its low dropout voltage, which ensures efficient operation even when the input voltage is close to the output voltage, thus maximizing battery life. The regulator also offers a low quiescent current of just 160µA, further extending battery runtime in portable applications.

The MAX8869EUE18 is equipped with a variety of protective features to ensure the stability and reliability of the end application. These include thermal shutdown, which protects the device from overheating, and short-circuit protection, which safeguards both the regulator and the load in the event of a fault condition. Additionally, the device incorporates a low-noise bypass pin that allows the use of an external capacitor to reduce output noise, making it suitable for noise-sensitive applications.

This LDO regulator is available in a compact 16-pin TSSOP package, which is ideal for space-constrained applications. Its small footprint, combined with a minimal number of required external components, enables designers to achieve a low-profile and cost-effective power management solution.

The MAX8869EUE18 is characterized for operation over the industrial temperature range of -40°C to +85°C, allowing it to be used in a wide variety of environments and applications. With its combination of features, performance, and packaging, the MAX8869EUE18 is a versatile power management solution that meets the needs of today's sophisticated electronic designs.
