MAX8718, MAX8719 High-Voltage, Low-Power Linear Regulators For Notebook Computers

The MAX8718 MAX8719 are micropower, 8-pin TDFN linear Regulators that supply always-on, keep-alive power to CMOS RAM, Real-Time Clocks (RTC), and Microcontrollers in systems with High-Voltage batteries. The circuits consist of a 100mA linear Regulator and a power-good Comparator (PGOOD) with fixed-output delay. Key features include wide input voltage range, low-dropout voltage, and low-quiescent supply current. Despite a miserly 25A (max) no-load quiescent current, the MAX8718 MAX8719 have good line- and loadtransient response and excellent AC power-supply rejection. They provide a clean fixed 5V or 3.3V output MAX8718 , or an adjustable 1.24V to 28V output MAX8719 , even when subjected to fast supply-voltage changes that occur during the switchover from battery to AC-adapter input power. The space-saving TDFN package has excellent thermal characteristics and tolerates up to 1951mW of power dissipation. Internal foldback current limiting and thermal shutdown protect the Regulator from overload and thermal faults. In addition to the main notebook-computer application, these devices are useful in other low-power, High-Voltage applications (4V < VIN < 28V) such as smart batteries, current control loops, telecom emergency power, and housekeeping power for off-line supplies. The MAX8718 MAX8719 are available in a thermally enhanced 3mm x 3mm, 8-lead TDFN package.
