Maxim Integrated's MAX8880EUT+T: Low-Dropout Linear Regulator

The MAX8880EUT+T is a high-performance, low-dropout (LDO) linear regulator from Maxim Integrated, designed to deliver a continuous output current of up to 200mA. This tiny, efficient regulator is ideal for portable applications where extended battery life is crucial. The MAX8880EUT+T operates from a wide input voltage range of 2.5V to 6.5V, making it versatile for various power supply scenarios.

One of the standout features of the MAX8880EUT+T is its low quiescent current, which is typically just 90µA. This characteristic is particularly beneficial in battery-operated devices, as it minimizes the power consumed when the device is in standby mode, thus prolonging battery life. Additionally, when the regulator is shut down, the supply current drops to a mere 0.1µA, further conserving energy.

The device comes in a compact SOT-23 package, which is highly favored for space-constrained applications. Its small footprint does not compromise performance, as it boasts excellent transient response and stability with low-value ceramic capacitors, making it a practical choice for modern, compact electronic designs.

The MAX8880EUT+T also features a low dropout voltage, typically 165mV at 200mA load, ensuring efficient operation even when the input-to-output voltage differential is minimal. This characteristic is particularly important for maintaining a stable output as the input voltage approaches the output voltage level, a common scenario in battery-operated devices as the battery discharges.

For protection, the MAX8880EUT+T is equipped with both thermal shutdown and short-circuit protection, safeguarding the device and the application against adverse conditions. Additionally, the regulator provides a logic-controlled shutdown input, allowing the power to be turned off, thus saving power when the device is not in use.

In summary, the MAX8880EUT+T from Maxim Integrated is a versatile, efficient, and reliable LDO linear regulator that is well-suited for portable devices requiring long battery life, minimal power consumption, and space-saving design. Its combination of features ensures that it can meet the stringent requirements of modern electronic applications.
