Maxim Integrated's MAX8878EUK Voltage Regulator

The MAX8878EUK from Maxim Integrated is a highly efficient, low-dropout linear voltage regulator designed to deliver a continuous output current of up to 150mA. This compact and versatile component is an ideal solution for space-constrained applications requiring a regulated power supply with minimal power loss.

Key Features

• High Accuracy: The output voltage is accurate to within ±1.5%, ensuring reliable and consistent performance for sensitive electronic circuits.
• Low Dropout: With a low dropout voltage of typically 165mV at 150mA load, the MAX8878EUK ensures efficient operation even when the supply voltage is close to the output voltage. This characteristic is particularly beneficial for battery-powered devices where maximizing the usage of available power is crucial.
• Thermal Overload Protection: The device includes built-in thermal overload protection that safeguards it from damage due to excessive heat and power dissipation.
• Current Limit Protection: The MAX8878EUK also features current limit protection to prevent damage from overcurrent conditions, enhancing the durability and lifespan of both the regulator and the overall system.
• Low Quiescent Current: Its low quiescent current of only 90µA (typical) makes it an excellent choice for battery-operated devices, as it helps to extend battery life by minimizing standby power consumption.
• Wide Operating Temperature Range: The device operates over a broad temperature range from -40°C to +85°C, making it suitable for use in various environments and applications.
