Maxim Integrated's MAX8878EUK28: Low-Dropout Linear Regulator

The MAX8878EUK28 is a high-performance, low-dropout (LDO) linear regulator designed by Maxim Integrated, a renowned leader in analog and mixed-signal products. This precision voltage regulator is engineered to deliver a fixed output of 2.8 volts, making it an ideal power management solution for battery-powered devices and other portable applications where energy efficiency is of paramount importance.

Key Features:

• High Accuracy: The MAX8878EUK28 boasts an impressive output voltage accuracy of ±1%, ensuring reliable and consistent performance for sensitive electronic circuits.
• Low-Dropout Voltage: With a low dropout voltage of typically 120mV at 150mA load, this regulator operates efficiently even when the input voltage is close to the output voltage, thus maximizing battery life.
• High Output Current: Capable of supplying up to 150mA of load current, it can easily power a wide range of ICs and other electronic components.
• Thermal Overload Protection: To safeguard against excessive temperatures, the MAX8878EUK28 includes built-in thermal overload protection that temporarily shuts down the regulator to prevent damage.
• Short-Circuit Protection: This device also integrates short-circuit protection, which limits the output current in case of a fault, thereby protecting both the regulator and the attached components.

Applications:

• Cellular Phones
• Portable and Battery-Powered Equipment
• Wireless LAN Devices
• Handheld Instruments
• PDAs and Mobile Computing

The MAX8878EUK28 is offered in a compact SOT-23 package, making it an excellent choice for space-constrained applications.
